Pediatric Gastroenterology and Nutrition

The Division of Pediatric Gastroenterology and Nutrition evaluates and treats a broad spectrum of digestive disorders in children from infancy to young adulthood.

With a multidisciplinary team that includes board-certified pediatric gastroenterologists, a pediatric nurse practitioner, gastroenterology nurses and dietitians, we provide state-of-the-art treatments, including the latest therapies for inflammatory bowel disease, and work closely with other subspecialists at the Herman & Walter Samuelson Children’s Hospital at Sinai to ensure high-quality, family-centered care. Our offices are located at easily accessible sites in Baltimore City, Mount Airy and Perry Hall.
