OCHN is contracted by the Michigan Department of Health and Human Services to lead a provider service network that assists approximately 29,000 Oakland County citizens at more than 400 service sites across the county. People who receive public behavioral health services through OCHN's provider network include those who have an intellectual or developmental disability, mental health challenge, or substance use disorder. Most of these individuals have Medicaid insurance coverage.

OCHN's goal is to ensure these individuals are aware of and have access to services and supports that will improve their health and quality of life, as well as ensure their engagement in full community participation. Its mission to “inspire hope, empower people, and strengthen communities” reflects an unyielding belief in a "Valuable System for Valued People."
