About Me

I am a board-certified internist, medical oncologist, and hematologist specializing in treating gastrointestinal malignancies, including colorectal, pancreatobiliary, and gastroesophageal cancers. I regularly participate in Memorial Sloan Kettering’s Colorectal and Hepatobiliary Disease Management Team meetings, in which patients’ treatment is discussed by a multidisciplinary team.

I see patients at MSK Commack, on Long Island, where my goal is to provide patients with high-quality care close to home.

In addition to providing patients with a range of standard treatment options, I enroll patients in clinical trials for newer therapies and refer patients to MSK’s Manhattan campus for any services or clinical trials that may not be available at MSK Commack. 

Through working closely with surgeons at MSK’s Manhattan location as well as radiation oncologists, radiologists, oncology nurses, nutritionists, and social workers at MSK Commack, I provide patients with individualized treatment plans.
