Our Team

Celiac Disease and Gluten Sensitivity Center photo

The team is comprised of board-certified pediatric gastroenterologists (physicians who specialize in diseases of the digestive tracts of children) and includes highly trained nurse practitioners as well as a registered dietitian. A registered dietitian is particularly important because treatment of celiac disease revolves around making dietary changes, which includes educating families and children on food choices, sharing eating strategies and recipes, reviewing shopping tips and providing ongoing support.

Anupama Chawla, MD - Director
Grace Gathungu, MD
Jeffrey Morganstern, MD
Lesley Small-Harary, MD

Supporting Specialists:
In some children, celiac disease may affect other body systems or other aspects of their health. Because we take an approach that supports the total health of your child, we make the following experts available to you if needed. They, too, become part of your child’s care team. These supporting specialties include:

Allergy and Immunology
