Get to Know Me

I am a board-certified breast surgeon who treats people with breast cancer. I see patients at Memorial Sloan Kettering Commack on Long Island, and perform surgery at the Josie Robertson Surgery Center in Manhattan.

I specialize in advanced breast surgery techniques including skin-sparing mastectomies, nipple-sparing mastectomies, and oncoplastic surgery. Oncoplastic surgery combines traditional breast cancer surgery with plastic surgery techniques by using hidden incisions and rearranging breast tissue to achieve the best possible cosmetic results for patients.

I am passionate about helping and supporting my patients throughout their treatment journey. I make it a priority to take the time to understand their needs and answer their questions during every visit.  My goal is to make my patients feel comfortable and confident with their decisions and guide them at every step. After I provide them with the most up-to-date information about their diagnosis and my recommendations, we work together to make decisions about a treatment and care plan that best fits their individual needs.

My research focuses on translating the results of important clinical trials that are potentially practice changing. I am investigating the best and safest ways to potentially implement those findings and incorporate them into everyday clinical practice. I am also focusing on innovation and using the power of artificial intelligence to improve diagnosis, treatment, and care delivery for patients.

When I’m not seeing patients, I enjoy spending quality time with my family and loved ones. Cooking with my family is one of my favorite things to do. I also love to stay active by working out and playing tennis and I love painting on canvas and exploring new art techniques.
