Who We Serve

Griffin Memorial Hospital provides in-patient hospital care for those in need of mental health & substance abuse services. We work with each person to identify specific needs and provide appropriate treatment. Shortly after admission, an individual begins to work with staff to complete a thorough physical, emotional, behavioral and social evaluation. They will become part of a treatment team that includes the individual and trained staff from psychiatry, social work, psychology, activities and nursing services. Based on the evaluations, a comprehensive treatment plan is developed to meet identified needs. This multi-disciplinary assessment and treatment approach is used throughout the hospital stay.

Information for Consumers, Families, Friends and the Community


Griffin Memorial Hospital was originally started as High Gate College, a girls' school established by the United Methodist Church, South in 1890, one year after the settlement of Norman. With competition from the University of Oklahoma, High Gate College closed its doors in early 1895 and was soon bought by the Oklahoma Sanitarium Company. In 1915, the State of Oklahoma bought the Oklahoma Sanitarium Company and renamed the institution Central State Hospital. In 1953, the hospital was renamed Griffin Memorial Hospital. Under the supervision of Dr. David Griffin, the hospital grew to over 30 buildings and three farms in its first 40 years. With a change in institutional care in the 1960s, the state built a Community Health Care Center on the hospital grounds.
