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.
