"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"

"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."

"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."

"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."

"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!"

"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."

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.

"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."

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."
