About

Bio

I am board certified in Internal Medicine and Gastroenterology/Hepatology. My interests include Fecal Microbiota Transplantation for relapsing C. Difficile infection, therapeutic endoscopy, ERCP for biliary disease, treatment of irritable bowl syndrome (IBS), inflammatory bowel disease (Crohn's Disease and ulcerative colitis), celiac disease., and colorectal cancer screening and prevention.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
