OPHS opened its’ doors in December, 2002, the Michigan Primary Care Association approached the Pontiac Health Initiative (PHI), collaboration between the City of Pontiac, North Oakland Medical Center, Pontiac Osteopathic Hospital and St. Joseph’s Mercy Hospital – Oakland, to collaborate on ways to improve the health status of residents in the Greater Pontiac area. The two agencies worked together to gather data and health statistics to support a request of funding from the U.S. Government. The PHI approached Oakland Livingston Human Service Agency (OLHSA) to serve as the fiduciary for the newly incorporated Oakland Primary Health Services.
In September 2002, OPHS was officially awarded a section 330 grant from the Bureau of Primary Health Care to deliver primary health care services to the medically underserved in and around Pontiac, MI.
OPHS was emancipated from its fiduciary in March 2003.
