"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 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."
