I am a cancer surgeon who specializes in treating patients with pre-cancerous and cancerous conditions of the pancreas, liver, bile ducts, stomach, and adrenal glands. I initially trained and practiced at Walter Reed Army Medical Center in Washington, D.C. During this time, I served one year on a forward surgical team in Iraq. Following this service, I practiced for 13 years as a surgical oncologist at Memorial Sloan Kettering Cancer Center in New York.

I enjoy getting to know my patients and delivering the highest quality of cancer care.
