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.
