- I became a pediatric surgeon first and foremost for the patients. I am excited to return from my surgical training in Montreal to the community where I grew up and studied, in order to serve the people here. I went to high school on Long Island and earned my professional degrees from the Stony Brook Medical Scientist Training Program. With the new Children’s Hospital at Stony Brook Medicine, I believe that we have an extraordinary opportunity to provide integrated, cutting-edge, and comprehensive pediatric surgical care. As a physician scientist, I am committed to advancing our understanding of pediatric surgery and improving our patients' lives.
