As a surgeon, I have pioneered several robotic and minimally invasive treatments for patients whose conditions were previously untreatable. I enjoy the intellectual and technical challenges that come with caring for people who have complex diseases and require surgical procedures.

My patients have various types of benign and malignant diseases of the liver and pancreas, as well as diseases of the thyroid, parathyroid, and adrenal gland. I am skilled in the latest minimally invasive surgical techniques, including the whipple procedure and robotic surgery, which allow patients to return home sooner and recover more quickly. Each patient is unique, which is why I work with a team of oncologists, radiologists, and rehabilitation specialists at Perlmutter Cancer Center to develop a coordinated plan of care that is tailored to each individual person.

At ºÙºÙÊÓƵ Hospital—Long Island our team’s surgical outcomes are among the best in the nation. Collaboration is key to our success—we schedule weekly meetings where clinical leaders from various disciplines meet to discuss plans of care for new and current patients.

I am an active member of the American College of Surgeons and the American Association of Endocrine Surgeons, among many other professional societies. My endocrine surgery outcomes have been widely published in peer-reviewed literature and I have been recognized by Castle Connolly’s “Top Surgeons†series.

My research is focused on improving outcomes for patients who require surgery for hepatobiliary, pancreatic, and endocrine diseases. This work complements my administrative role as the chairman of Quality Assurance for the Department of Surgery, as well as my role as institutional cancer liaison physician to the American College of Surgeons’ Commission on Cancer. In these capacities, and in my own scholarly work, it is my goal to develop innovative ways to make surgery safer and more effective, while improving outcomes for patients with malignant disease.
