"Dr. Rufner helped confirm a diagnosis for me after experiencing mystery symptoms for over two years. I felt like my concerns were taken seriously at this clinic and I am very thankful and actively working on symptom management. As part of my diagnosis I had an endoscopy at their procedure center and it went very smoothly there as well."
"I have been a patient of Dr Trouillot for many years. He has always been attentive and open to answering all my questions and concerns. His care has resulted in total remission of my UC. I could not be more satisfied with his his care and the service provided by his staff."
"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!"
"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.... $$$$$$$$$$$$$$$$$$"
"I have been a patient of Dr. Kevin Rufner with Colorado Gastroenterology for many years, and it has always been a positive experience. Dr. Rufner is a kind and caring human being who really listens to his patients. He never makes me feel rushed or hurried, gives me up-to-date information about my health complaints, and always comes up with a complete plan of care for every issue. Additionally, his staff are friendly and supportive. I cannot recommend Dr. Rufner enough. He is an excellent doctor with an excellent staff."
"I have been a patient of Dr. Sieja for many years. He has helped me through a lot in the past few years. He is caring and very easy to talk to. HE LISTENS!!!"
"The nurse was SO funny and friendly, all of the people working in the office were sweet and helpful, and the doctor was so informative. I felt listened to and felt like I really understood the full extent of the processes I was going to go through."
"Dr. Sieja listed to what I had to say. Scheduled appointments for me the very next day, in order to get to the root of my problem. I am thankful for having him as my doctor."
"This is the best doctor experience I have ever had. Dr. Rufner is so kind and takes the time to explain everything so well. The office staff were incredible- kind and helpful!"
"Dr. Rufner surprised me with his attentiveness and listening skills. He took his time making me feel extremely comfortable and confident in my care plan. He told me his goal is to make me feel empowered."
"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."
"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."
"My visit with Dr. Rufner was a great first meeting. 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 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."
"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"
"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 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."
"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."
"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."
"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."
