Personal Statement

Being a pediatric gastroenterologist allows me to do what I love the most -- to be able to help children with their ever-challenging gastrointestinal problems. At Weill Cornell, I am a part of a unique institution, where comprehensive patient care, family integration, and pioneering research are driving forces that subsequently help patients and their loved ones to receive the best gastrointestinal care.

While I practice in the whole range of digestive diseases in pediatric patients, I devote extra focus to the study and treatment of motility disorders. These are a unique subset of disorders that cause the body to fail to move nutrition normally through the length of the digestive tract. I lead the Pediatric Motility Center at NewYork-Presbyterian/Komansky Children's Hospital and Weill Cornell Medicine, the only center that the full range of diagnostic and treatment capability in the New York metro area. I strive to provide the most advanced, thoughtful, and family-oriented care to all patients, including yours.
