Internal Medicine

I am a medical oncologist and internist specializing in the care of patients with malignancies originating from the genitourinary tract, specifically prostate, bladder, kidney, and testicular cancers. I practice at Memorial Sloan Kettering’s regional site in Commack, Long Island. I am proud to be part of a dedicated multidisciplinary team that includes surgeons, radiation oncologists, oncology nurses, a social worker, and a nutritionist in providing optimal cancer care to patients who wish to be treated close to home on Long Island.

I am also a member of MSK’s Genitourinary Oncology Service. I regularly attend disease management team meetings, where I meet with colleagues from the Manhattan campus and other regional network sites to discuss patient care and to review treatment advances. Through this interaction, I participate in several clinical trials open in Commack and am able to facilitate enrollment into studies open only at MSK’s Manhattan campus.

As a medical oncologist, my constant goal is to deliver compassionate cancer care of the highest quality to all of my patients. I strongly believe that it is my duty to treat each patient as an individual, always taking into account differences in medical, psychosocial, and cultural backgrounds.

I am fluent in English and Farsi.
