About Us

Surgeons at Weill Cornell Medicine are widely recognized and respected for their expertise and for being at the forefront of advances in the field.

Our surgeons treat a wide range of conditions, adopting and developing advanced methods for the surgical treatment of most abdominal disorders, including hernias, and conditions of the stomach, intestines, gallbladder and spleen.

At Weill Cornell Medicine, we perform repair of hernias, treat patients with surgical emergencies, perform biopsies, and remove growths from different parts of the body. Procedures are frequently performed using minimal access (laparoscopic and endoscopic) techniques.

We use the most advanced innovations, coupled with compassionate care to guide our patients through their individual surgical experiences.
