"I have only met with her once as a new doctor for me. She was thorough with her interview of me. She provided good advice and wrote down specific instructions for me to follow. I look forward to working with her in the future."

"I've seen Dr. Kevin Rufner for a few visits over the last year while we get my treatment plan changed up, and I'm extremely satisfied with his care. I've had IBD for 40 years, and lived in different places, so I've seen many GI Docs over that time. You won't go wrong with him as your GI Doc."

"Dr. Sieja listed to what I had to say. Scheduled appointments for me the very next day, in order to get to the root of my problem. I am thankful for having him as my doctor."

"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."
