Endocrine and Minimally Invasive Surgery

About Us

The section of Endocrine and Minimally Invasive Surgery at Weill Cornell Medicine aims to provide comprehensive care for a full range of diseases of the thyroid, parathyroid gland, adrenal gland, as well as endocrine tumors of the gastrointestinal tract and pancreas — from the more common and benign disorders to relatively rare cancers.

As healthcare providers, our surgeons treat patients as individuals with specific needs and combine cutting-edge technology with a comprehensive team approach to personalize treatment.

We emphasize strong collaboration within our teams to bring a unique multidisciplinary care that is patient-centric and novel. This enables us to work together to conduct collaborative research needed to develop and improve our expertise.

In addition to providing outstanding individualized clinical care, we are committed to advancing the field of endocrine surgery through research and education with the goal of finding better treatments that not only cure patients but also improve their quality of life.

Our multidisciplinary team is comprised of thought leaders and practicing researchers dedicated to the studies of tumor biology, who continue to be well published and highly respected within the community.
