Our Team

Our team of board certified pediatric gastroenterologists is complemented by highly trained nurse practitioners, a registered dietitian, and Inflammatory Bowel Disease (IBD) and celiac educators. We work closely with our state-of-the-art endoscopy unit staff as well as motility laboratory staff. Pediatric anesthesiologists provide anesthesia for all endoscopy patients - a minimally invasive procedure that is used to diagnose a number of gastrointestinal issues including celiac disease. Together, we provide multidisciplinary care drawing upon all the resources and specialists of our academic medical center as needed, including pediatric surgery, pediatric radiology, pediatric anesthesia, pediatric intensive care and more.
