Our Physicians

Please meet our medical staff at Long Beach Gastroenterology Associates. Our group is comprised of board certified gastroenterologists who are highly trained and experienced. We were fortunate in 2009 to add a Physician’s Assistant to our staff to assist our physicians in providing best in class care for our patients suffering from digestive disorders.
