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.

Dr. Rufner helped confirm a diagnosis for me after experiencing mystery symptoms for over two years. I felt like my concerns were taken seriously at this clinic and I am very thankful and actively working on symptom management. As part of my diagnosis I had an endoscopy at their procedure center and it went very smoothly there as well.

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.
