Sovereign Medical Services

Sovereign Medical Services was a private U.S. healthcare services company that operated and managed a multi-specialty outpatient physician network under the Sovereign Health System brand in New Jersey and nearby markets. The business appears to have focused on physician practice operations, ambulatory care delivery, and supporting infrastructure such as patient portal and health IT tools rather than drug R&D. Publicly available materials describe a broad clinical network spanning primary care, specialty care, surgery, radiation therapy, and ancillary services. The company was headquartered in Glen Rock, New Jersey and was associated with founder and CEO John H. Hajjar, MD. As of 2024-2026, the legal entity appears to have entered bankruptcy proceedings and should be treated as inactive as an operating company.
