"Doctor Rufner isn't just great he's amazing! Very thorough, derailed, took the time to explain things in great detail, didn't rush at all just simply amazing. You can tell he really cares and has compassion for me as a patient. I also noticed he was trying to take more of the natural approach of healing instead of expecting a medication to mask everything. I really wish all doctors now days were as organized and patient as he is. In this day in age it's very hard to find good care, I feel I have truly gotten extremely lucky"

"I have been to other Gastro office and this one by far has been 100 better than I could have ever expected! Dr. Brenner is amazing and seems to truly care about her patients! I would whole heartily recommend this practice!"

"Dr Ruffner is a very informed and progressive physician who relies on his education, experience and collaboration with others to be effective for his patients. He has been the only physician who didn’t quickly dismiss my digestive issues as IBS and truly explored deeper which paid off. He listens and takes his time to respond and explain. You will never feel rushed. In the past I’ve had issues with inept administrative and assistant staff but so glad to have NeeNee as the face of this practice. She’s personable and pleasant to work with."

"I had to wait for a while due to Covid and also a downed room computer, but I was kept informed and even Dr. Brenner came to the waiting room to let me know. I appreciated this. Another enjoyable follow up visit with Dr. Brenner and I left with the feeling that I was cared for and my concerns were addressed. Thank you."
