For more than 50 years, Hamilton County Developmental Disabilities Services has provided educational, vocational, and residential support and services to thousands of individuals with developmental disabilities (DD). Our agency traces its roots back to 1947, when parents who were concerned about the lack of support for their children with DD created a formal organization to provide services and educational programs.

In 1967, Ohio established the county board system giving each county responsibility for providing home training, preschool and developmental classes, community classes, sheltered workshops and adult activity centers for people with intellectual and developmental disabilities.

Throughout the years the needs of individuals and their families, as well as federal and state mandates, have dictated agency growth and change. Recently our focus has shifted away from legacy programs like adult work and activity centers to supporting people in the community through partnerships with hundreds of agencies, businesses, organizations, neighborhoods and people in Greater Cincinnati.

In 2009, the agency changed its name from Hamilton County Board of Mental Retardation and Developmental Disabilities (HCBMRDD) to Hamilton County Developmental Disabilities Services. This change was due to longstanding advocacy efforts of people with disabilities and their families who successfully removed the term “mental retardation” from many official references. In 2016, Ohio Gov. John Kasich signed legislation changing all references to the "R" word in state documents to "person with an intellectual disability.”

Today, Hamilton County DD Services supports more than 8,000 people annually by providing case management, monitoring service quality, and funding services provided by our community partners.
