    "I had a wonderful experience! He took my concerns seriously, answered any question I had with sincerity and knowledge, and helped me understand how to manage my issues without shame or guilt. He was responsive, knowledgeable, honest, and overall very attentive. I always have a ton of questions for my doctors and he never made me feel rushed or bad for asking. Definitely recommend!"

    "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."

    "Dr. Rufner is excellent. This was only my first appt. so I will come back and update this review after my second. I was able to really talk to him and tell him everything and he listened really well and explained in detail what I needed to be educated on and the procedures we would be doing together to find answers to get to recovery. I also can't say enough good things about NeNe his scheduler. She has a great caring personality on top of being efficient. What a find in an employee. I will again up date this later but I recommend going to him for any GI needs."
