"Jun 2024 Dr. Rufner performed an endoscopy and colonoscopy on me this month. I greatly appreciate his diligence in determining the cause of my symptoms and offering expert health recommendations. In my opinion, he's an awesome doctor. I feel confident trusting his diagnosis and course of treatment. He's thorough and takes time to explain his diagnosis and treatment options. He never gives me the rush-act. He's caring and compassionate. I highly recommend Dr. Rufner for your gastroenterology needs. Oct 2023 Dr Rufner is excellent! I love how he drew a picture of what was going on. He knew what the problem without ever physically examining me. This doctor really knows his stuff! He spoke quite authoritatively regarding my diagnoses and offered valuable explanation regarding his determination of what was causing my symptoms. I felt I could place my confidence in this physician because he was transparent as he offered knowledge about what was causing my symptoms. I felt better emotionally, mentally, and I began tfelling better physically after following his prescription. I highly, highly recommend Dr Kevin Rufner and his medical office. The office staff were excellent. I will definitely recommend this gastroenterology practice to my friends and family."

"Colonoscopy: If you need to have one, Dr Rufner in Lowry is the GI doc to see. Dr Rufner teams with experienced anesthesiologist and nurses. He was one of Dr Mallory, retired GI who taught gastroenterology at UC medical school to this generation of doctors. Would recommend using zinc oxide/ diaper rash ointment BEFORE drinking bowel prep. Takes 72 hours to rebuild your microbiome."

"Prep routine was the worst part - surflava tasted terrible and had a slimy texture - gag index was high - left me feeling queasy. Procedure was easy, check-in was efficient, all my concerns were addressed, and everything was fully explained. Some of the staff didn't seem to have much of a sense of humor. Being a repeat 'customer' I feel that the overall quality of the treatment has remained consistently high."
