Personal Statement

Giving back to my community has always been a driving force behind any endeavor I undertake, and my focus as a physician is no different. I was born and raised in Brooklyn, New York and was fortunate enough to complete my medical and specialty training in the same borough that helped raise me. Because of this, I feel that I am uniquely equipped to provide the medical care required to serve the complex needs of the diverse population that comprises New York City. I believe in a well-rounded, inclusive approach to patient care that involves compassion, empathy and understanding, not just with my patients but also with their families and any other people involved in their care. I am excited to be part of a team that incorporates a comprehensive, multidisciplinary approach to ensure that patients receive the best possible care.
