Brief Intro

As a Gastroenterologist with an additional two-year fellowship in Inflammatory Bowel Disease from UNC at Chapel Hill, an internationally recognized Inflammatory Bowel Disease Center of Excellence, I strive to compassionately increase and modernize the quality of care for all my patients. Complementing this scholarly approach, I practice a style of medicine rooted in old-school tradition, where medical care begins with listening to the patient and building a strong doctor-patient relationship. - David Grunkemeier, MD
