I am a board-certified internist and medical oncologist with special expertise in the diagnosis and treatment of patients with cancers of the head and neck and gastrointestinal malignancies. I collaborate with a multidisciplinary team of physicians, surgeons, radiation oncologists, pathologists, and radiologists to bring the best possible care to patients who wish to be treated close to home on Long Island.

To provide optimal care for patients with gastrointestinal or head and neck cancer, it is often necessary to coordinate care with other specialists such as speech and swallow therapists, nutritionists, physical therapists, and social workers. We are fortunate at Memorial Sloan Kettering Commack to have access to these resources, ensuring that patients receive state-of-the-art cancer care in a safe and supportive environment.
