"Good first visit"

"I have had ulcerative colitis for about 20 years. I was diagnosed when I was in 4th grade. Over those two decades, I have had doctors who don’t take into account how I am doing. Just what my test results say. Dr. Rufner is not one of those doctors. Of course, he relies on test results, but he also values my own personal feelings a lot. He is also VERY up to date on the latest science and has some well-informed suggestions on how I can best manage my condition. I would absolutely recommend Dr. Rufner to anyone looking for help!"

"I saw Dr. Kevin Rufner for the first time today, for long standing Crohn's Disease. Based on only one very extensive meeting, I was extremely impressed with Dr. Rufner and will absolutely continue seeing him. I feel very fortunate to have connected with him. I've had Crohn's for over 40 years, so I've seen my share of GI doctors."

"The staff were all very personable. All current safety guidelines were in place. Dr. Rufner listens, and discusses in detail your situation. He wants to be sure you understand, and does not rush the appointment."

"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."
