Why did you choose to specialize in Gastroenterology?

I love being a Gastroenterologist because of my breadth of practice and my impact on health.

As a Gastroenterologist, I get to solve complex medical diseases with keen intellect, counsel on general health and well-being akin to a primary physician, and perform endoscopy to treat anatomical disease as a precise surgeon…often all in the same day!

Through Gastroenterology I get to prevent cancer on a daily basis, help ill young patients return to healthy productive lives, help older patients maintain their health and quality of life, and be the caring hand during tragic illness.

Do you have a specialty of interest in Gastroenterology?

I treat all aspects of gastrointestinal and liver disease with a specific interest in inflammatory bowel disease and immune disorders of the gut.

What do you and your family enjoy doing in your spare time?

I enjoy skiing, mountain biking, and cycling here in the amazing Rocky Mountains. I enjoy escaping to the ocean for scuba diving and the feel of sand on my feet. And if the weather is bad, I stay inside and play the blues on my guitar.

Kevin is great , I had problems with my upper abdomen, consulted many GI doctors , he is the best to diagnose , listening and answering questions.

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.

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.
