He’s also the first doctor that has genuinely cared about my liver diagnosis and how to reverse the damage of my liver. I’m comfortable talking to him about anything that’s going on and also respect that he personally understands mental health on top of endocrinology.

"Jun 2024 Dr. Rufner performed an endoscopy and colonoscopy on me this month. I greatly appreciate his diligence in determining the cause of my symptoms and offering expert health recommendations. In my opinion, he's an awesome doctor. I feel confident trusting his diagnosis and course of treatment. He's thorough and takes time to explain his diagnosis and treatment options. He never gives me the rush-act. He's caring and compassionate. I highly recommend Dr. Rufner for your gastroenterology needs. Oct 2023 Dr Rufner is excellent! I love how he drew a picture of what was going on. He knew what the problem without ever physically examining me. This doctor really knows his stuff! He spoke quite authoritatively regarding my diagnoses and offered valuable explanation regarding his determination of what was causing my symptoms. I felt I could place my confidence in this physician because he was transparent as he offered knowledge about what was causing my symptoms. I felt better emotionally, mentally, and I began tfelling better physically after following his prescription. I highly, highly recommend Dr Kevin Rufner and his medical office. The office staff were excellent. I will definitely recommend this gastroenterology practice to my friends and family."
"Colonoscopy: If you need to have one, Dr Rufner in Lowry is the GI doc to see. Dr Rufner teams with experienced anesthesiologist and nurses. He was one of Dr Mallory, retired GI who taught gastroenterology at UC medical school to this generation of doctors. Would recommend using zinc oxide/ diaper rash ointment BEFORE drinking bowel prep. Takes 72 hours to rebuild your microbiome."
"excellent competent and friendly staff. from front desk, to Scott, the doctor and finally young lady doing scheduling were great. very efficient and well informed. highly recommend"
"Prep routine was the worst part - surflava tasted terrible and had a slimy texture - gag index was high - left me feeling queasy. Procedure was easy, check-in was efficient, all my concerns were addressed, and everything was fully explained. Some of the staff didn't seem to have much of a sense of humor. Being a repeat 'customer' I feel that the overall quality of the treatment has remained consistently high."
"Dr Sieja reviewed my medical records, and after a thorough examination, he advised me to see a different GI with a unique skill set. He called the specialist and discussed my case with him. My visit with Dr. Sieja was positive and informative, he explained my medical issues in great detail and ways to correct it. I appreciated his honest opinion regarding my case."
"The pre-op communication was excellent. I knew what to do and what to expect. The process of checking in and getting prepped was fine. The procedure was as expected. Quick, painless and easy."
"Dr Trouillot explains everything very simply and listened to my concerns. I would recommend him. He helped me with my issues and I would go back if I needed any assistance."
"My procedure completed by Doctor Thomas Trouillot M.D. was outstanding! The doctor explained everything about the procedure that he was going to complete and asked if I had any questions prior to proceeding. The doctor also explained there was no time limit on completing the procedure, it depended on what was found. I can highly recommend Doctor Thomas Trouillot M.D.!"
"I am very grateful to Dr. Rufner and the staff for their high professionalism and excellent care. I felt like I was in good hands. Highly recommend. 👍👍👍"
"Dr Rufner was very professional and courteous. After the procedure, he talked to me about his findings and explained what it meant and when I should return."
"I get really good attention and am listened to. When I call with a question, I get a follow up call back. I had labs drown and Dr. Brenner called me herself to tell me that they were normal. Often times a normal result has not been call personally by the treating physician. It is here. I’m impressed and I’ve had IBS for over 30 years now. So, that’s saying a lot"
"Thanks to Dr Brenner my colonoscopy was amazing! The anesthesiologist was helpful and amazing also! I would recommend this office to anyone that has to have a colonoscopy. The entire staff was 10 Stars if that's a good rating... 20 stars is better! Thank you! G.Terry"

"As always, the staff are wonderful and return calls promptly. Dr. Rufner listens to what you have to say and never makes you feel rushed. Unfortunately I have had to return many times because of my stomach issues but he always tries to figure out different ways to help me. I trust Dr. Rufner with my health and wouldn't go anywhere else."
"I felt I was well taken care of throughout the procedure. I didn't go with five stars because the procedure was delayed. This was a colonoscopy and as you know they're not very much fun. Other than that everything was fine."
"Dr. Rufner was thorough with his questions and exam. And he gave me some suggestions for the near future. He seemed genuinely interested and capable."
"Dr. Rufner is wonderful. Where do I start. First, he really knows his stuff. But I guess that’s a low bar for a specialist. More importantly, he took the time to explain everything to me in great detail and didn’t rush anything. Second, he is one of the most personable and relatable doctors I’ve seen In my longish life. I highly recommend him"
"This is a very clean and modern location. Everyone was very nice and patient. Dr. Brenner's bedside manners are excellent and appreciated very much. I felt comfortable and at ease. Thank you!!"
"Colorado Gastroenterology Aurora CO provided one of the best colonoscopies I’ve had. Staff is most caring and respectful. A very comfortable no-rush outpatient facility. The oral fluid home preparation is much improved (More tolerable, taste, Less time & volume, part-1 the night before, part-2 The morning of medical procedure). A+ experience!"
"Great experience. Dr. Rufner was very down to earth and explained the procedure in a way that we all understood. The hardest part, was in the waiting room where a couple people I think were from Mars. Had a good 30 minute nap at IT WAS OVER."
"Procedure was professional. But even tho I followed the prep directions to a T, my system was not fully prepped for the colonoscopy. Therefore, the doctor couldn’t see much of my colon. I continued to have diarrhea for four more days. Also, the first nurse couldn’t insert one, and then two blood ports in my right hand, the second nurse installed a port successfully on my left hand on the first try. It was a difficult day, made more difficult by these near misses."
"Dr. Brenner takes the time to listen to your concerns, comes up with a few action plans, follows up with you and gives you full bodily autonomy to make the choice that you feel most comfortable with at that time. I highly recommend her!"
"I recommend Dr. Rufner to anyone who is confused with his/her stomach situation. It took him about 10-15 min to explain what’s going on with my stomach. He even drew a picture of my stomach problem. He has recommended me some very affordable but great OTC pills to deal with my acid reflex. He answered all my questions even those which sounded silly. Great doctor!"
"Dr. Rufner was very kind, patient, and helpful. He's a very nice gentleman and there to listen and help meet me where I was at. Very knowledgeable and insightful, I appreciate his support and help with my personal/physical health."

"Amazing doc. I have very high expectations of people, especially doctors. Which, often leads to disappointment.

Added bonus: he draws you pictures as he explains things. ;)"

"Dr. Rufner was highly recommended by my oncologist. Dr. Rufner is knowledgeable about mast cells, and it extremely hard to find doctors who understand the complexity of mast cells. I traveled from a different state to have a small procedure with him. Dr. Rufner is super kind, and I felt very safe in his care. I believe he is brilliant about GI, and I trust him completely! He listens carefully, explains clearly, and spends a lot of time with me. I have never felt rushed at all in my appts with him. I am very blessed to have him as my GI doctor, and I THANK HIM for EVERYTHING!!"

"Dr. Rufner is the BEST! He took a lot of time during my appointment to explain my G.I. issues and devised a plan for treatment and further testing.

"Dr. Trouillot is a very knowledgeable doctor with a caring professional bedside manner. He listened to everything I had to say and made me feel comfortable talking about gastrointestinal issues.

I would recommend him without any reservations to anyone needing to see a gastroenterologist."

A few times (when I was unable to schedule an appointment ) he called me to discuss my problem. I would highly recommend Dr. Ruffner."
"Stomach issues are no joke, and I wanted to start this review off by saying that I've gone through six or seven years straight with severe abdominal pain, nausea, sickness, missing school, missing work, doctor appointments, pills, and various diagnoses that have not helped me at all. It's hard to find someone that can help. Then I found Dr. Brenner. When I went into the office for the first time, I was extremely nervous and had little hope for help. The staff was very sweet. But when I met Dr. Brenner for the first time, I was expecting her to be like all of the others. I can officially say that I am now in remission after seven years thanks to her. She examined my previous medical reports without bias and listened to me with understanding. She had told me that there was no proof I had any of the diseases that these other "doctors" were diagnosing me with, that I didn't need to take all kinds of pills, and gave me advice and tips on how to help myself with home remedies with whatever I may be going through (severe abdominal pain for example). I'm now thankfully taking one pill that for sure helps me, but is not required, and I can eat all kinds of food now that I've never been able to eat. Dr. Brenner is sweet, honest, and very caring with her work. I plan to go to see her for as long as I can."
"I just had my first consultation appointment with Dr Trouillot. What I found most valuable about him was his attentiveness, a great listener. Too many physicians are pressed for time and are challenged with allowing patients to explain their symptoms and history in detail. Dr Trouillot gave me the time to explain and I never felt rushed or dismissed."
"The appointment didn't feel rushed. I felt like I was fully listened to and that what I said was taken into account in deciding a path forwards. Additionally my questions were all answered clearly and I walked out understanding what would happen next."
"Dr. Trouillot is a very professional Dr who wants the best for his patients. He goes the extra lengths to know his patients, what there symptoms are so that they can be treated for the right symptoms. If you schedule a procedure with Dr. Trouillot he will double check and triple check what your procedure is and make sure you are there for the right reason. Also, Dr. Trouillot staff is very kind and professional as well. They ask you the (patients) questions so the Dr. already has an idea what you are coming in for. I would highly recommend Dr. Trouillot and staff to friends, family, and anyone looking to have a procedure done the correct way."
"Dr. Sieja and his team are thorough and do a great job at explaining any diagnosis you may have. I felt confident being in his care and he has a great bedside manner."

He listened to all my concerns without judgment and I could tell he truly understood what I was saying! His medical assistant Cydney was also wonderful! I highly recommend Dr. Rufner!"
"I was referred to Dr Brenner by my PCP for a consultation regarding ongoing gastrointestinal issues.

I found her to be knowledgeable, empathetic and helpful in deciding on an action plan."
"I have been going to Dr Rufner since 2014 when my pancreas blew up. Dr Rufner has been my rock ever since and helped me walk through a very rough road of multiple ERCPs (over 12), stones and major surgery. I feel like I owe my health and life to him. He is extremely knowledgeable, kind, calming and you cannot do better than Dr Rufner!"
"Dr. Sieja & his medical team have gone above and beyond to meet my 48 year old concerns & recent health scare. As a Pediatric Regional RN the service delivered & received are representative of humble expertise. Dr. Sieja carries an energy of compassionate care and role models excellence for his team. Truly appreciate the courtesy & Care demonstrated prior to my intervention. Peace & Grace, Heath"
"I have had ulcerative colitis for about 20 years. I was diagnosed when I was in 4th grade. Over those two decades, I have had doctors who don’t take into account how I am doing. Just what my test results say. Dr. Rufner is not one of those doctors. Of course, he relies on test results, but he also values my own personal feelings a lot. He is also VERY up to date on the latest science and has some well-informed suggestions on how I can best manage my condition. I would absolutely recommend Dr. Rufner to anyone looking for help!"

"Doctor Rufner isn't just great he's amazing! Very thorough, derailed, took the time to explain things in great detail, didn't rush at all just simply amazing. You can tell he really cares and has compassion for me as a patient. I also noticed he was trying to take more of the natural approach of healing instead of expecting a medication to mask everything. I really wish all doctors now days were as organized and patient as he is. In this day in age it's very hard to find good care, I feel I have truly gotten extremely lucky"
"Dr. Rufner listens and hears what the patient has to say. Then doctor and patient can come up with a solution. I've been seeing Dr. Rufner for several years and wouldn't consider seeing anyone else. He helped me through my recovery after colon cancer. I highly recommended Dr. Rufner."
"I have had good experience with Dr. Trouillot. He is very detailed and tries to take time to explain the diagnosis and treatment plans. Helped me through some difficult times."

Having been a nurse for thirty years and having worked GI I think he is a exceptional physician. I am very impressed with his care."
"I've relied on Dr. Sieja over 17 years for his medical care, comprehensive knowledge, kindness, responsiveness, gentleness, communication, discussing treatment options, and evaluations in treating my inflammatory bowl disease.

"i felt that when I was there 2 yrs, ago I felt that Dr. S. was more patient and listened more.{perhaps he did not like the fact that I turned down the coloscopy.) I question why I have to have invasive procedures when less alternatives have not been explored. They own the center. Caching, caching.... $$$$$$$$$$$$$$$$$$"
"Dr. Rufner read over my existing file before my first appointment, listened to my concerns, and formulated a plan. I appreciate his willingness to problem solve with me."

In a telehealth appointment today, we reviewed my past medical history, discussed a new diagnosis and her continuing role in my care with respect to the diagnosis, she developed a plan and goals for the next six months, ordered a new prescription for me and requested copies of some recent studies - all in short order. I have always found Dr. Brenner to be knowledgeable, honest and well-prepared. I am privileged to have been her patient for many years and will continue to be her patient as long as she will have me!!"
"I am very happy with the way dr Brenner treated my problems . It deserves 5 stars, but I just want to complain about their answering service. It is very difficult to call them , It happens many times that they don't answer the phone , they leave me on hold then it is disconnected and they never call back, I leave an urgent message with the answering service ( I was feeling very dizzy after taking a medication for my problem...) and they never call me back , So I had to call another doctor to reassure me and answer my question....... And so on.... It is a pity to have a very good Doctor with a very bad answering service. You cannot rely on it"
"Great doctor, very thorough, takes time to explain diagnosis in detail. Excellent professional and personal manner. Only complaint is very poor telephone appointment system"
"I like her writing down directions because I usually can't write fast enough to get them down myself. She quickly gets to the point, and we are done with a hopeful direction to go next."
"I've seen Dr. Kevin Rufner for a few visits over the last year while we get my treatment plan changed up, and I'm extremely satisfied with his care. I've had IBD for 40 years, and lived in different places, so I've seen many GI Docs over that time. You won't go wrong with him as your GI Doc."
"Excellent and informative tele-health appointment on July 15 with Dr. Rufner, who is always personable and who gets to the nub of the matter and explains clearly whatever action is next required. Inspires confidence. A+"
"Make sure you bring a mask (unless you're reading this from a post-pandemic world in which case, don't rub it in), I forgot mine and almost had to miss my appointment because of it. Luckily there are nice dentists next door with masks to spare."
"Dr Rufner does his best to understand his clients needs and make a plan with their goals in mind. He looks to help to recommend for wellness considerations, not just diagnose the IBD and check in once a year. I have been very satisfied with the care that he has provided for my condition over the past 3+ years. My only wish was that the office staff was a little easier to reach by phone. I have sometimes had to call 2-3 times to get through to a person because they are a really busy office."
"Dr. Rufner always takes the time to deeply listen to the GI issues I have faced, and then puts together comprehensive plans of how to move forward with treatment."
"Dr. Ruffner is the very best! He has His patients best interest at heart and is very much in tune with the needs of those that are lucky enough to have found their way to be in His s care!"
"So I'm not a patient of his, but my boyfriend is. So far he has been the only doctor to take his llness seriously. My boyfriend has gastroparesis and it has been a rough couple of years, but we've been lucky to have come across Dr. Rufner. The approaches he is taking have helped us find out so much in such a small amount of time, much faster than his past doctors have performed. Would recommend him over and over."
"Dr Rufner took the time to listen carefully to my issue and then explained to me in detail the possible problems and solutions. He was very professional and personable and I greatly appreciate him researching out my file prior to my office visit. He attention to detail and professionalism is greatly appreciated."
"Dr Brenner has always been very responsive to my illness and needs. I do have some questions about the side effects of the biologic she’s proposing but I am confident the she will explain completely! Thank you, Dr. Brenner!"
"Dr. Rufner really listens to what I have to say and can always make me understand what's going on and make suggestions to help me. I would highly recommend him. He is a great doctor!"
"I had to wait for a while due to Covid and also a downed room computer, but I was kept informed and even Dr. Brenner came to the waiting room to let me know. I appreciated this. Another enjoyable follow up visit with Dr. Brenner and I left with the feeling that I was cared for and my concerns were addressed. Thank you."
"The staff is friendly and prompt. I like working with Dr. Seija. He listens, encourages me to ask questions, empathizes and explains my health needs in a very understandable way. I'm grateful to have found him."
"Very professional and explained everything in detail. Covered a lot in short time and was very attentive to my questions and concerns. The video worked well for a time then interference was bit hard to understand luckily we had covered most of what were my concerns. Dr Rufner went the extra mile and called to make sure we had covered everything A+++"
"This is under Susie Arnold. Dr. Rufner is Amazing. He never makes you feel rushed. he explains everything, answers all your questions, draws pictures and always remembers who i am even when it has been 2 years since i have been there. The staff is always friendly and helpful. Because of Covid they have been short staffed."
"Dr. Rufner's approach in helping my mom was excellent He took the time to get down to her level to speak to her, looked directly at her and listened carefully to everything she said. He explained his concerns and plans with her in a language she could understand and made her feel very comfortable with next steps."
"This is the second time I've worked with Dr. Rufner. He's very good at answering all my questions, was open and clear with my options. I didn't spend much time waiting and was very comfortable throughout the visit."

He took all the time I needed to answer my many questions and make me feel very comfortable going forward with my procedure, especially in this time of Covid-19! Dr. Rufner has a very kind and understanding manor and I would highly recommend him to anyone looking for a gastroenterology doctor!"
"Dr. Brenner is a beautiful person,understanding and compassion she will take care of you and she always be concerned if you are following you treatments and helping you to get better and healthy to have a better life..she will listen to you concerns and you problems and she will focus to get you healthier. I love Dr. Brenner 💜"
"I had a colonoscopy with Dr Brenner she was so pleasant and made me feel comfortable. The staff and nurses that worked with her were absolutely amazing. So kind and caring. I would recommend them to anyone and I would definitely feel completely comfortable with Dr. Brenner handling any Gastrointestinal problems I had."
"Dr Rufner listened carefully to my medical issue, asked me relevant questions and provided me clear explanations of my likely condition. Dr Rufner provided his plan to help me. I left his office with confidence that I am in very good hands with a knowledgeable and caring doctor."
"I've been seeing gastroenterologists in various cities for the past 20 years. Dr Kevin Rufner is BY FAR the most informative, patient, kind, and knowledgable doctor I have worked with. He is a member of various advisory boards and study groups around the state and country and so is informed about the latest clinical studies, and he is always willing to take as much time as I need to explain my current health status, his recommendations and reasoning behind them, and address any concerns or questions I have. I have never felt rushed or confused, and even when the news isn't great I leave his office feeling empowered about next steps. I cannot stress enough how much I have preferred working with him over any other GI I've seen. I used to leave my doc's office in tears so frequently because of feeling confused and scared about what I was going through, that I started taking a full day off work whenever I had an appointment, regardless of appointment time. This pattern ended when I started seeing Dr Rufner. I have also never posted a review for a doctor before because I've never had an experience worth sharing until now. I've recommended Dr Rufner to a number of friends and colleagues. I'd also like to point out that every staff member I've encountered at the Colorado GI Ogden Street location has been patient, friendly, helpful, and easy to work with. They've also contributed to my general feelings of ease whenever I need to visit the office."
"I had a great experience seeing Dr. Rufner. He was exceptionally friendly and professional, listened carefully to my conditions and concerns, and most importantly he explained the medical information very clearly. Would highly recommend him."
"Dr. Rufner has been my best gastroenterologist and I've had quite a few. I've had some say they didnt know what was wrong but Dr. Rufner knew what it was and how to treat. I have been going to him about 6 years and highly recommend him."
"I was very pleased with my visit last week with Dr. Rufner. He took the time to sit down and talk about my case. He didn't hurry through the visit. He acted liked he really cared---unlike some other specialists I have seen. It was good to have someone so knowledgeable and understanding both."
"Great visit where I came away understanding what was actually happening, and a thoroughly explained approach to resolving the issue. Highly recommend."
"Had my first visit with Dr. Rufner by telemedicine. It was nothing short of amazing. I felt totally comfortable talking with him. He had some amazing ideas about how to help me, and came up with a sensible plan - all in 20 min!"
"Dr. Rufner is Amazing. he explains everything, I never feel rushed, He answers every questions and he will even draw pictures for you :) he is a nice warm person who will make you feel comfortable right away. I have been going to see him for a few years and this has never changed."
"Dr. Rufner was kind and patient, taking the time to walk me through the GI issues I had and why I had them, and suggested several different routes of treatment. Everyone in the office was also pleasant and professional. Great experience all around!"

"Dr R was very friendly, took time to explain what was probably going and ea of the respective trt. Plans. One of the best med. off. visit ever. I would highly recommend"
"Dr. Rufner was honest, clear in his communication style, and warm. I felt comfortable from start to finish at my appointment and he was great at giving a full explanation of what would or would not be cause for concern. Though the place wasn't a fancy office space as I have seen in most clinics, I wouldn't let that sway your decision. The gal at the front desk was super friendly and I felt like they cared about me as a patient. I recommend this practice!"
"Dr. Rufner is one of the most truly caring doctors I’ve had. He has, quite literally, held my hand learning how to live with my horrible disease and is still able to help me focus on the positives. I highly recommend him. With that being said, the supportive staff leaves much to be desired. Any time I’ve called with a question or request and left a message for an MA I either get NO response at all or it takes numerous calls and it may or may not be resolved. I continue to see Dr. Rufner in spite of the assistants because HE is great."
"Amazing doctor, patient first mentality. Takes as much time as you need to really understand your concerns and create a mutual treatment plan. Also, very active in local community in regards to research and alternative treatments. Couldn’t recommend him enough."
"I have consulted with Dr Rufner several times now and each time he is kind, thorough, and empathetic. I enjoy talking to him and would highly recommend him."
"I felt that Dr. Rufner was very engaged and interested in helping me get closer to resolving my gastro issues. The initial consultation went well and I think that Dr. Rufner and his team will provide me the best possible care with any future issues I may encounter."
"Dr. Sieja was very detailed and thorough in discussing the issues that I had recently experienced. He was able to clearly articulate certain things that I needed to change that included both lifestyle and dietary changes. I would strongly recommend Dr. Sieja for anyone that needs to consult with a Gastroenterologist."
"Dr. Rufner was very knowledgeable and answered all my questions I had before I could even ask them. The prompt response and fast scheduling from them made my experience here way better than the last Gastroenterologist I was at."
"Dr Brenner has seen me since 2012. She diagnosed me and helped me through my ups and downs. She cares, she listens and always just wanted to make me feel better. She is knowledgeable and really explains things so you understand what is going on. I refer anyone that needs a GI doctor to go here. The staff went above and beyond to help me with an insurance issue as well..."
"Dr. Brenner and staff were fantastic! Dr. Brenner was personable yet very professional, thorough and knowledgeable. I felt that I can trust her professional opinions completely. Thank you, Dr. Brenner and the staff!"
"Received the lab report on mychart, but I don't know how to interpret the high and low indicators as to what significance they have for me. I would like some additional feedback on those with a flag on the levels shown."
"Dr Brenner has the best bedside manner and one of the most professional physicians I have seen. I would have no hesitation in recommending her to anyone - particularly in this sensitive medical situation."
"The wait time was very short. Dr. Rufner was very attentive and I appreciated that he took the time to review my medical records prior to my first visit with him. He was honest, kind and humorous. I liked that he explained multiple different treatment options for me to choose from. I’m very impressed and happy with the care I received."
"So I'm not a patient of his, but my boyfriend is. So far he has been the only doctor to take his llness seriously. My boyfriend has gastroparesis and it has been a rough couple of years, but we've been lucky to have come across Dr. Rufner. The approaches he is taking have helped us find out so much in such a small amount of time, much faster than his past doctors have performed. Would recommend him over and over."
"I saw Dr. Kevin Rufner for the first time today, for long standing Crohn's Disease. Based on only one very extensive meeting, I was extremely impressed with Dr. Rufner and will absolutely continue seeing him. I feel very fortunate to have connected with him. I've had Crohn's for over 40 years, so I've seen my share of GI doctors."
"My experience with Dr. Rufner was incredible. He listened to my concerns and was very informative and polite. Will definitely be back here if I have any additional gastro issues!"
"Dr. Brenner was professional and kind. She took plenty of time to talk through my symptoms and took the situation very seriously. I really appreciate her ability to think beyond just GI possibilities, and her commitment to figuring out what's wrong with me. I am so appreciative!"
"Dr. Rufner was attentive and very informative. Took the time to explain and address any of my concerns. Front desk staff as well as the MA was very friendly."
"I have been to other Gastro office and this one by far has been 100 better than I could have ever expected! Dr. Brenner is amazing and seems to truly care about her patients! I would whole heartily recommend this practice!"
"I saw Dr Brenner years ago and decided to do a follow up. She was as wonderful as I remember 9 years ago. Getting an appointment scheduled was not an issue, and I was happy to do a an appointment over the phone as well. Great experience."
"Dr Ruffner is a very informed and progressive physician who relies on his education, experience and collaboration with others to be effective for his patients. He has been the only physician who didn’t quickly dismiss my digestive issues as IBS and truly explored deeper which paid off. He listens and takes his time to respond and explain. You will never feel rushed. In the past I’ve had issues with inept administrative and assistant staff but so glad to have NeeNee as the face of this practice. She’s personable and pleasant to work with."
"Dr. Rufner thoroughly explained what he performed in a very understandable way. All the results were, also, communicated very well. He provided some suggestions on how to supplement my diet going forward. I would highly recommend Dr. Rufner"
"I really felt heard. Dr Rufner was truly interested in my situation. I felt like I could trust him. I’ve not had great experiences with gastroenterologists and my expectations were low, dr Rufner completely blew my expectations through the roof. What an amazingly smart man with terrific bedside manner. I’m super happy to have him in my life."
"Both Dr. Rufner and Scott, the Front Office Manager, are best-in-class. Dr. Rufner has excellent bedside energy, and he is a very intelligent and thoughtful professional. Scott is perhaps the most proactive office employee I have ever encountered -- refreshing! I highly recommend this office!"
"Dr. Rufner is excellent. This was only my first appt. so I will come back and update this review after my second. I was able to really talk to him and tell him everything and he listened really well and explained in detail what I needed to be educated on and the procedures we would be doing together to find answers to get to recovery. I also can't say enough good things about NeNe his scheduler. She has a great caring personality on top of being efficient. What a find in an employee. I will again up date this later but I recommend going to him for any GI needs."
"The staff were all very personable. All current safety guidelines were in place. Dr. Rufner listens, and discusses in detail your situation. He wants to be sure you understand, and does not rush the appointment."
"My visit with Dr. Rufner was good but trying to communicate with the doctor and office is impossible. Six calls last week and no response. Makes me concerned about a response from him should there be difficulties after a procedure."
"Dr Brenner was great! I have been to 4 other GI physicians and I truly feel she has helped me the most. She did a very detailed history and physical and asked me lots of questions concerning my GI symptoms. I left feeling that my symptoms were for the first time have been addressed with great advice on how to manage my GI symptoms with a followup. She encouraged me to call with any further questions."
"Everyone, everything was done in a very comfortable fashion for me. All of the individuals that assisted through the procedure were fantastic. I was completely comfortable and at ease in throughout the entire experience."
"So I'm not a patient of his, but my boyfriend is. So far he has been the only doctor to take his llness seriously. My boyfriend has gastroparesis and it has been a rough couple of years, but we've been lucky to have come across Dr. Rufner. The approaches he is taking have helped us find out so much in such a small amount of time, much faster than his past doctors have performed. Would recommend him over and over."
"Went in for a visit because of increasing symptoms of Gerd. Not a long wait time and received instructions and a 6month follow up visit. Felt relieved and I wish I went in weeks earlier!! Always a good visit with helpful advice with Dr. Brenner."
"I get treated like I’m the only person there. Everyone is so friendly and professional I just love it. It makes going to the doctor not so bad. I met Dr. Rufner for the first time today. He has a wonderful bedside manner. I don’t remember laughing so hard in a doctor’s office in my life as I did today. I would recommend Colorado Gastroenterology to anyone. Way to go CG!!!"
"I have been a patient of Dr. Ruffner for a few months. He was 1/2 hour late for my last appointment ( mix-up of files?), but he did spent a lot of time with me. He explained the results of my scope in detail ( including a drawing!). We discussed the next steps and options for treatment. I do think he is a caring and compassionate doctor. He understands my frustration and promises we will find the right treatment."
"Dr. Rufner is amazing! When I leave the office I feel like he listened to me and came up with a solution. He also explained in detail exactly why he was choosing a certain medication for me. After years of no explanation for my stomach pain, he found an answers for me. I highly recommend him."
"The Staff is very professional and nice. Dr. Rufner really takes the time to listen to you and he makes several recommendations on how to get you back to feeling good again."
"Dr Seija and everyone at the office are so lovely and professional. Sometimes there is a bit of a wait for an appointment because they are so popular, but it's worth it. It's always an informative visit and I come away feeling reassured with ways to manage different conditions."
"(this is Torie Vandeven, not angie rovetta.. she is my partner and emergency contact, fyi.) Dr. Brenner is an excellent listener and is focused on my particular health issues. She is very thorough, and successfully diagnosed a condition that other gastroenterologists were unable to do.tav"
"Dr Brenner was very helpful with my stomach and throat. She explained the 3 items that I may be having. She decided to start with a "Flip". Scheduled this for Dec 26. After results, she will go to the next step."
"I loved Dr. Brenner! She’s knowledgeable, focused, willing to listen, very straight forward (I like that) and caring. She’s down to earth, no beating around the bush, explains everything till you’re confident you understand. The office was very efficient in getting procedures scheduled, gave clear, written instructions, and answered all my questions."
"Dr Rufner is super personable, knowledgeable, and I feel I can trust him and the answers he finds. He listens to everything you say and is very good at explaining what is going on and the game plan ahead. Very easy to talk to."
"Dr. Rufner is just amazing! His treatment plan got me into remission, and it is always a pleasure to visit him. I’m not one of those people who are afraid of doctors/hospitals, but if I was Dr. Rufner would most certainly change my mind in that regard. He is very attentive to your concerns, and always explains his treatment decisions thoroughly. Every time I leave his office I feel confident that we have made the right decision for me and my treatment plan. Thank you Dr. Rufner!"
"I have been a patient of Dr Brenner for approximately 10 years. I have personally referred many of my own patients and colleagues to her. She is exceptional as a physician and kind and caring personally. I found her office to be well organized and well set up to follow covid 19 guidelines. As always, I had a pleasant experience."
"My partner Mark says Rufner is great, willing to spend time with patients. His office staff is personable, efficient, professional. Top notch service. Worked with my insurance. No problems."
"Dr, Rufner talked through actions steps for my stomach issues and helped rule out illnesses based on my history. He was helpful and informative, however the appointment was extremely rushed. I wasn’t able to get all my questions answered and he rushed through explanations of the recommendations he was providing. I hope to continue with Dr. Rufner over the coming months and then I’ll be able to give a more accurate description of his care."
"Kevin Rufner is the 3rd GI doctor I have gone to and the only one who has sat down and actually listened to the issues I had and helped me understand them. Definitely recommended."
"Dr. Rufner is awesome. In less than 30 minutes he explained to me about my multiple health problems and what could be causing them. Been waiting 20 years for some of the news i got today. He is very compassionate, makes sure i understood everything and he has a great caring personality"
"Amazing! They actually answer their phone. They actually make an appointment when they answer the phone. How is it they can do that? No one else in gastro does that. "Sarcasm." They took very good care of us totally worth the drive from the Springs where no one answers their phone or website requests for appointments. I hope they stay amazing but sick people need to know they can find care for gastro issues without the hassle. Stay amazing and be blessed!"
"I went to see Dr. Rufner today, and the overall experience was fantastic. The receptionist was very courteous and friendly. I only waited a few minutes, and then was called into the medical exam room. When Dr. Rufner arrived, he took the time to listen, and then evaluate an appropriate course of action. He was extremely knowledgeable in his field, and at the same time he communicates in a manner where you can fully understand the theory behind his recommendations. Great doctor, and great human being."
"If it matters, I had a good experience. My procedure was painless, I feel good the next day without any adverse effects. They even called the next day to make sure I still have a pulse. Never hard to get them on the phone and everything was spelled out nicely. I recommend."
"In August I had a colonoscopy with Dr. Rufner at the Golden location, and a few weeks later, my husband had his done in Denver. Dr. Rufner is the best in every way you want a doctor to be. He explains EVERYTHING and spends as much time as you need. I guess that's called a good bedside manner. Additionally, the folks that work on his team are fantastic. The receptionist immediately greets you with a big smile and makes you feel welcome. Then, the nursing staff takes over and they couldn't be any nicer and did I mention how efficient, professional and kind they all were? Anyway, I can't say enough positive about these folks and want to thank everyone at Colorado Gastroenterology for making a difficult procedure almost enjoyable."
"I have spent plenty of time in doctor's offices and hospitals and unfortunately am only 30. I have genetics that make me very prone to colon cancer, so I met with Dr. Frank and had a colonoscopy done as a result. They found a polyp, removed it and I have a plan moving forward. Overall, with Dr. Frank and everyone in the office, they were extremely pleasant all the way over to the Denver Endoscopy Center. I have had terrible experiences and this was the complete opposite. I had also called another local gastro group and received a different experience. Regarding the poor review below about insurance and costs. I can't remember her name, but a representative of the office reached out to me about my insurance, clearly explained costs, potential for payment options, etc. Since I am young, my insurance didn't off the bat consider this preventative. I had genetic testing done and she was able to detail what I needed to do with the insurance company to get it to be preventative. She even allowed me to merge a call with her and my insurance provider. Couldn't have been happier. Thank you."
"Dr Brenner is the BEST--very well qualified as a gastroenterologist. Her bedside manner is so caring and an excellent listener who provides the best care possible--IBS seems to be the "in" disease and she is most sympathetic in handling issues surrounding IBS and providing answers and remedies ""
