Dr. Alexandra Capece is a board-certified breast surgeon who works to provide a concierge level of care for each of her patients. She offers women personalized treatment options, uses the latest developments in breast cancer care, and strives to make every patient feel comfortable.

Dr. Capece specializes in oncoplastic procedures and wants to help patients feel confident in their bodies post-surgery. As far back as she can remember, Dr. Capece wanted to be a physician. She was drawn to the operating room from a young age.

Dr. Capece chose to work with breast cancer patients because she found inspiration in their strength and resilience. She’s proud to work within the Northwell Health network to ensure patients receive high-quality care in every aspect of their treatment.

“[It was] my first time seeing Dr Capece, and she was wonderful. She listened to my concerns and questions, and that made me feel good."
