    "I was very pleased with my visit last week with Dr. Rufner. He took the time to sit down and talk about my case. He didn't hurry through the visit. He acted liked he really cared---unlike some other specialists I have seen. It was good to have someone so knowledgeable and understanding both."

    "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."
