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.
