About Me

I am a surgeon who has cared for patients with cancer and benign tumors for over a decade. I specialize in breast and endocrine surgical oncology.

At The Mount Sinai Hospital and The Tisch Cancer Institute, I am so proud of our multi-disciplinary teams that provide the most advanced options available to patients in the New York area. My team's goal is to provide every patient with the broadest set of choices, because there are often several "right answers" for the treatment of these conditions. As a surgeon, my role is to help my patients navigate this process and make the most informed decisions. I am passionate about shared decision-making, the practice by which we work together to develop a personalized treatment plan. I see patients at Mount-Sinai Union Square and Chelsea.
