Harbor View Medical Services

Harbor View Medical Services was a multi-specialty physician practice organization affiliated with John T. Mather Hospital in Port Jefferson, New York. The group employed primary care and specialty physicians and operated outpatient practices across Suffolk County, providing services including cardiology, endocrinology, family medicine, internal medicine, neurology, vascular surgery, and other specialties. It was not a drug-development biotech or pharma company; rather, it functioned as a healthcare delivery organization. In January 2024, Mather Hospital announced that Harbor View Medical Services, P.C. had been renamed Mather Medical Group to align the physician practices more closely with the hospital’s brand. The organization appears to have continued operating clinically under the new name rather than being shut down or acquired.
