At Mount Sinai-Union Square, you will find gastroenterologists and liver specialists who can help you with any of the above symptoms. We are your convenient one-stop location for consultation, diagnosis, treatment, management, and education about your condition. All our doctors are on the faculty of the renowned Icahn School of Medicine at Mount Sinai, and have close relationships with our colleagues at our flagship hospital, The Mount Sinai Hospital, which has been recognized by U.S. News & World Report® as having one of the finest gastroenterological and gastrointestinal surgery programs in the country. This makes innovative clinical trials, specialized testing, and nutrition counseling all accessible downtown.
We also work closely with the Autoimmune Diseases Center at Mount Sinai-Union Square, as many gastroenterological conditions are caused by disorders of the autoimmune system.

Are you 45 or older? Have you been screened for colon cancer?
Colon cancer is one of the most preventable cancers when detected early, and screening is the best way to protect yourself. A colonoscopy not only finds precancerous polyps before they turn into cancer but also allows us to remove them during the same procedure. We are specially trained in endoscopic techniques to ensure a thorough and safe exam, giving you the highest level of expertise in both prevention and early detection.
Our procedures are performed at East Side Endoscopy (just a few blocks away from Mount Sinai-Union Square) which was recently voted Best Ambulatory Surgery Center in New York City for 2025 by Newsweek. We are among a select few centers nationwide using AI technology during colonoscopies. This real-time system helps our physicians detect even the smallest polyps, improving prevention outcomes and ensuring that your colonoscopy is as thorough as possible.
If you are in good health and qualify for our Colon Cancer Screening Program, we can arrange for you to have a colonoscopy without having to have an appointment with a physician before or after. Simply fill out the form below with some basic medical questions. A member of our team will reach out to you to schedule a virtual visit, help arrange your procedure, and discuss the process. If you prefer, you can also meet with a gastroenterologist first.
