Founded2005

Atrius Health is a prominent non-profit healthcare leader based in Eastern Massachusetts, dedicated to providing comprehensive, high-quality, patient-centered care to over 700,000 adult and pediatric patients. It was formed from the merger of several established physician groups, including Harvard Vanguard Medical Associates, Dedham Medical Associates, Granite Medical Group, and PMG Physician Associates. Atrius Health offers a wide array of services, including primary care, pediatrics, over 50 specialties, and ancillary services like laboratory and imaging. In early 2022, Atrius Health became part of Optum, a division of UnitedHealth Group, with the shared goal of advancing value-based care and improving patient outcomes and experiences in the region. It continues to operate under the Atrius Health name across its numerous clinical sites.
