I am an experienced board-certified gastroenterologist, trained at The Johns Hopkins University School of Medicine and Duke University Medical Center.

I have been on the American College of Gastroenterology Practice Management Committe, which included medical legal issues, and co-chaired a national conference for the ACG on practice management.
