Why choose us?

Expert care

The Division of Colorectal Surgery at Northwell Health is comprised of board-certified colon and rectal surgeons across New York City, Westchester and Long Island. Our nationally recognized surgeons regularly publish peer-reviewed articles and lecture on surgical techniques and advancements in the field. 

Innovative research

Research propels surgical care. That is why our surgeons are actively involved in research at the Feinstein Institute for Medical Research. Through research conducted in the biomedical research division, we are able to uncover the causes of colorectal diseases and develop new clinical treatments that are less invasive and have fewer risks of complication.

State-of-the-art techniques

Minimally invasive surgery is the future of surgical care. At Northwell Health, we recognize the benefits of minimally invasive technique over traditional surgeries. That is why we offer a variety of minimally invasive surgeries for colorectal diseases, including colon and rectal cancer. Our surgeons are specialty trained in the latest techniques in minimally invasive surgery. Patients can be confident in the fact that they are being treated by physicians with expertise. They help patients choose the best options and use of the latest technology. We are also training the next generation of surgeons through our fully accredited colon and rectal surgery  fellowship  and minimally invasive surgery fellowship programs.
