Patient Care Philosophy

I believe that visits should consist of an open dialogue between patient and provider to come to a plan together by shared decision-making. By placing a high priority on listening to patients and understanding their perceptions about their symptoms, and by taking time to educate patients within the context of advanced gastroenterology knowledge and evidence-based medicine, patients are empowered and involved in their own care.

I think that Dr. Schomaker was very good at taking the time to explain things and go over options that we not pertinent to the GI visit in case something else is the cause. Great doctor, highly recommend!
