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.

I am the Chief of the Melanoma Service at Memorial Sloan Kettering Cancer Center (MSK), where my practice is devoted solely to the care of people with melanoma. It is my privilege to lead an outstanding group of medical oncologists, nurses, and researchers with world-leading expertise in the treatment and management of melanoma. Many FDA-approved therapies for patients with melanoma were developed by our team, including the combination of nivolumab (Opdivo®) and ipilimumab (Yervoy®). The regimen has since been recognized as a major scientific advance in melanoma by The American Society of Clinical Oncology.

Our service not only takes great pride in offering our patients the latest and best interventions available, but also in affording access to drugs in development when standard approaches might not be helping. People with melanoma have more therapeutic opportunities than ever before, and I believe that we as a field can do even better. To that end, I have spent my professional life working with oncologists from around the globe to expand the portfolio of melanoma treatments, and I am glad to provide fellow doctors with advice when they reach out to me with questions on the optimal approaches or how to manage side effects.
As a board-certified medical oncologist, I spend most of my time with patients. Creating close, trusting relationships with patients and their families as we craft treatment plans tailored to their unique needs is one of the most gratifying aspects of my work. I appreciate that a diagnosis of melanoma can understandably make one feel nervous, and I believe that it is critical to take care of the whole person and their support network in a friendly and personal way. I look forward to caring for you and your loved ones as if you are one of my family members.
In my free time, I enjoy skiing, hiking, and trying to keep up with my toddlers and triathlete wife.
