We post reviews for MSK healthcare providers who have at least 30 patient experience surveys completed. If you do not see reviews for a provider, it may be because they do not yet have enough survey responses, or the provider may not be part of the group of healthcare providers included in the survey.
Only outpatient providers are included in the survey. Healthcare providers who only work in the hospital or in urgent care are not included in the survey. Pathologists or researchers who do not provide direct care to patients do not have reviews.

Surgery
I am a breast surgical oncologist who specializes exclusively in the treatment of breast diseases. I perform all aspects of breast cancer surgery. I also have extensive experience in caring for people with benign disease. I see patients at MSK Westchester, where I work closely with my colleagues in radiology, pathology, plastic surgery, medical oncology, and radiation oncology to deliver the highest quality care to our patients.
During the past several years, my research has focused on understanding the causes of lymphedema. Lymphedema is a chronic arm swelling that may occur if all of the underarm lymph nodes have been removed. I have also studied ways to find signs of lymphedema early on in women with early-stage and advanced breast cancer. Recently, my research has been focused on reducing how often lymphedema occurs by finding ways of removing fewer underarm lymph nodes, particularly for women who have chemotherapy before surgery. By improving our understanding of the side effects of breast cancer treatment, we can work to enhance the quality of life for everyone we care for. When I meet with my patients, I always want them to walk away from the appointment with a clear understanding of their diagnosis and our treatment recommendations. To do this, we spend time discussing all aspects of their care plan. Each plan is tailored to the individual person and circumstances. When concerns come up, like recurrence of cancer or lymphedema, I talk through each treatment option. I explain how treatments can be used to avoid complications as much as possible. I aim to instill each of my patients with a sense of confidence that they will receive excellent care, and that I am here to help every step of the way.
