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 understand that receiving a cancer diagnosis is difficult not only for the patient, but also for their entire network of support, because my decision to become a medical oncologist was motivated by the loss of a family member to cancer. This perspective guides my approach to patient care. To each patient visit, I bring empathy and compassion for the emotional side of a cancer diagnosis.
Beyond support, another principle of my care philosophy is education. Over the years, I have drawn upon my interactions with patients to develop a fact sheet that breaks down the elements of the disease and its treatment options. We go over the sheet together, talking about aspects like staging and the different types of treatment modalities. I make a point of taking the time to thoroughly characterize the disease and the available treatment options to empower my patients with the information they need about their diagnosis.
My practice is located at MSK Westchester in West Harrison, New York. Here, I work closely with a multidisciplinary team of surgeons, radiation oncologists, pathologists, nurses, and other specialists to provide the best care for our patients and their families. When I am not seeing patients, I am working to expand our regional care network. As the Medical Director of Strategic Partnerships at Memorial Sloan Kettering Cancer Center (MSK), I build relationships with partner hospitals around our regional locations in Long Island, New Jersey, and Westchester to support our goal of extending care closer to home for our patients outside of Manhattan.
I am also actively conducting research into the development of blood biomarkers for patients with melanoma whose tumor carries a specific mutation that can serve as a measure of how much melanoma is in the body. In time, I plan to evaluate these biomarkers’ utility in colorectal cancers in a clinical trial at MSK. I am passionate about improving therapeutic strategies for the treatment of both melanoma and GI cancers and have been fortunate to have my research supported by the American Society of Clinical Oncology.
