"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. I found him to be patient, caring, knowledgeable, and thorough. I highly recommend him for any G.I. issues. He is far and above other G.I. doctors, I have seen in the past."

"I had a wonderful experience! He took my concerns seriously, answered any question I had with sincerity and knowledge, and helped me understand how to manage my issues without shame or guilt. He was responsive, knowledgeable, honest, and overall very attentive. I always have a ton of questions for my doctors and he never made me feel rushed or bad for asking. Definitely recommend!"

"Dr. Trouillot was very knowledgeable and spent a lot of time during my initial appointment. He added me on to his busy schedule for an upper and lower scope in two days. Dr. Trouillot followed up with biopsy results within one week and took time to explain results and plan of care. 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 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."
