Nutrition Center | Meet Our Team

Our team of dietitians is passionately dedicated to finding answers for our patients and their families. With over 50 registered dietitians and a staff of nurses and technicians, we work together to help children with common or complex gastrointestinal, liver and nutritional problems. We can help children with inflammatory bowel disease, celiac disease, eosinophilic gastrointestinal disorders and short bowel syndrome, to name a few.
