To better serve the local community, we have opened a spacious new office at 5 Cuba Hill Road in Greenlawn that houses more than 20 specialties, as well as onsite radiology and laboratory services, all under one roof. With state-of-the-art equipment, a team of highly skilled physicians, and services that include primary care, cancer and hematology, and a comprehensive Women’s Center, our office brings the medical excellence of Mount Sinai home to our Suffolk County community. We are also pleased to offer conveniences such as extended hours, easy scheduling, ample parking, greeters, and welcoming waiting areas to ensure your visit with us runs as smoothly as possible.

As a multidisciplinary office, we have specialties in areas ranging from allergy to urology, all working together to provide you with complete, comprehensive health care.
