As usual, Dr. Trouillot and the Denver Endoscopy Center were very professional while still being very personable. I will continue to use Dr. Trouillo in the future.
Dr. Brenner is wonderful, she really cares about helping one feel better.
Thank you Dr. Sieja & Team for taking such great care of me. I was not overly excited for my 1st colonoscopy but everything about it was efficient & everyone was professional & friendly. Keep up the great work!
My consultation with Dr Trouillot was prompt and fruitful. Looking forward to seeing him again.
All went very well. Excellent experience
As always, Dr. Trouillot was thorough and systematic in his review of my symptoms. He explained his formulation and proposed treatment plan completely, and helped me sign on to it. Dr. Trouillot is an excellent physician and I can recommend him without reservation
I literally cannot imagine better care than that provided by Dr. Trouillot and the entire team at Denver Endoscopy. Gazillion stars!
The procedure went smoothly from start to finish. Instructions were thorough and all staff member were professional and helpful
Great as always. Very professional atmosphere.
I cannot stress this enough- Dr. Rufner is the best doctor that I have ever had in my life. I came to him incredibly ill from a flare-up. I was currently going to Rocky Mountain Gastro, where I experienced medical neglect. I had anemia due to the flare up, had lost 15 pounds and was experiencing medical grade fatigue. He saw right away and very clearly that they were not treating my flare up correctly for my UC as a whole correctly. He put me on meds and I was feeling better within a week. I think he saved my life. Dr. Rufner is caring and empathetic- He genuinely cares about his patients. He will sit and listen to your questions- I have never felt rushed. He is the first GI doctor that has sat with me and explained what UC is- and I was diagnosed back in July 2019 and started seeing him March 2023. He not only talked achieving remission, but all around wellness within my disease. Go to him! You truly won't regret it.
everyone was very kind and made me feel very comfortable
Dr. Rufner was incredible! He listened and heard my GI concerns and proposed a few solutions for me to choose from. I would recommend Dr. Rufner and his team to family and friends!
I have been seeing Dr Brenner for over a decade and now she is taking care of my husband. She is amazing...to the point, compassionate and extremely knowledgeable...we appreciate her expertise and advice. Highly recommend.
Also my husband and I have both done colonoscopy and endoscopy and Dr Brenner, her staff and hospital settings are so comfortable and make the process so easy.

The care was excellent. The doctor, and staff were caring, and professional.
Dr Rufner is an excellent doctor. He is well informed on current research regarding liver enzymes/function. He takes the time to educate patients in a way that is understandable and he spends time answering questions without making patients feel rushed.
True patience’s advocate. Thank You
Kindest, most compassionate Dr. I've had. Always went above and beyond what was expected. I've been a long time patient, and highly recommend her.
