Our office in Englewood Cliffs, NJ

Conveniently located in Bergen County, they began performing Colonoscopy and Upper Endoscopy (EGD) in their Medicare approved Ambulatory Surgery Center almost 20 years ago. Our new, state-of-the-art medical offices and ambulatory endoscopy center opened in June of 2011, and is conveniently located in Englewood Cliffs, NJ, just minutes from the George Washington Bridge and accessible by public transit. This new Medicare approved facility affords patients access to our physicians at times that are convenient to them, while eliminating much of the inconvenience and anxiety that may be associated with having their colonoscopy or endoscopy performed in a hospital setting. For those patients that choose to have their procedure performed at the hospital, our physicians maintain privileges and are closely affiliated with two of the area’s most respected hospitals: Englewood Hospital and Medical Center in Englewood, NJ and Holy Name Medical Center in Teaneck, NJ.

Our practice participates in most major medical plans and accepts various payment methods. We are committed to excellence in the field of Gastroenterology and to providing the highest standard of care in a modern and up to date setting that is also welcoming and comfortable for our patients. All of our staff are dedicated to ensuring that our patients are treated professionally and with compassion to make your visit a positive experience.
