As a native Long Islander, competitive athletics were a big part of my upbringing. As a former competitive soccer and tennis player, and now an avid weekend warrior, I understand how upsetting and derailing an injury can be to an athlete of any level. For this reason, I feel incredibly fortunate to be an orthopedic surgery sports medicine specialist focusing on disorders of the knee, hip, shoulder, and elbow.

My goal as an board certified orthopedic surgeon is to provide comprehensive care to all my patients. I believe in the importance of educating patients about their injuries so they can be active participants in their treatment decisions. Through both nonsurgical and surgical methods, my goal is always to help patients return to their preinjury performance level, whether that be competitive athletics or backyard softball with the kids.

I have had the privilege of providing general and sports-specific orthopedic care to numerous patients and athletes. Throughout my career, I have had the opportunity to be a part of the medical teams providing care to the athletes of Stony Brook University, Washington Football Team, Auburn Tigers football program, Tuskegee Golden Tigers football program, Pensacola Blue Wahoos Minor League Baseball team, and numerous local high school athletic programs.

At NYU Langone Hospital - Long Island, I am honored to be part of the attending staff committed to the education of our medical students and residents. Throughout my career, I have been extremely fortunate to have learned from amazing mentors. Similarly, I look forward to providing mentorship and guidance to the next generation of orthopedic surgeons.
