I found Dr Shumaker to be articulate, knowledgeable, and easy to work with. He is a very skilled surgeon and can clearly explain what he intends to do and why. He exudes a sense of knowledge and competence. I was especially impressed that he not only came into my hospital room the morning of my surgery, but he was also there when I came to. At each point, he was more than willing to answer any of my questions. The only negative comment I can make is a complaint about how long I had to wait to see Dr Shumaker for my initial visit.

I've been going to Dr. Shumaker for over 15 years for microscopic colitis (collagenous colitis) and he is the best. Has done multiple colonoscopies with patience and understanding. This condition causes uncontrollable, explosive diarrhea with no cure and has me on the best course of treatment I have had to date. Not only that, he is easy to talk to about it, understands how embarrassed and uncomfortable I feel about this condition and how it affects me, my life and family. I would recommend him to anyone.

Dr Shoemaker has been managing my ulcerative colitis for somewhere around 10 years now (after my previous doctor retired). During that time, I’ve had almost as many colonoscopies there, and many office visits. I feel very fortunate to have Dr Shoemaker caring for me. He is simply outstanding, and I hope to stay with him for a very long time. If you’re looking for an extremely good GI specialist, I can highly recommend him. You won’t be disappointed.

Colonoscopy care was excellent. The intro to clinic, nurses, cleanliness, and anesthesia, procedure and Sedation all went very well. Dr Shumaker explained the results thoroughly and understandably. We will utilize the Clinics services in the future.
