About Me

I am a board-certified medical oncologist with expertise in breast cancer and gynecological cancers such as ovarian, uterine, cervical, and vulvar cancer. I am a member of Memorial Sloan Kettering’s Breast Cancer and Gynecologic Disease Management Teams and actively participate in conferences with other MSK experts in these fields. 

After completing my oncology training at MSK in 2001, I joined the medical team at the Hauppauge facility, which was shortly moved to the brand-new Commack regional care facility. I practiced in Commack until 2006, when I became part of the team at MSK Rockville Centre. Throughout my time at MSK, I have strived to provide high-level medical care, with compassion, to my breast and gynecological cancer patients. 

My colleagues and I offer a multidisciplinary approach to treating breast and gynecological cancers. We have access to new and advanced treatments in medical oncology as well as state-of-the-art radiation oncology. We also have expertise with many novel chemotherapies, targeted therapies, and monoclonal antibody treatments and access to all of the resources and expertise of MSK’s Manhattan location, but in a setting closer to our patients’ homes. 

In both breast and gynecological cancers, our disease management teams are using special DNA analysis to pinpoint genetic abnormalities that are specific to an individual’s tumor. The results of these molecular tests may help to determine which targeted therapies could be most effective for the patient in the future.

As part of our research efforts, we are actively enrolling patients in a growing number of clinical trials at MSK Rockville Centre, allowing patients to receive the most advanced care closer to home in Long Island. We offer a warm, intimate environment, where doctors, nurses, and support staff collaborate with local physicians and facilities to take care of the medical, social, nutritional, and psychological needs of our patients.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
