ADDP Members at the 2015 Annual Conference

The Association of Developmental Disabilities Providers (ADDP) is a state-wide association that focuses exclusively on issues relating to developmental/intellectual disabilities, brain injury services and autism. Our excellent working relationships with the Department of Developmental Services, MassHealth, The Arc of Massachusetts, and the Brain Injury Association of Massachusetts allow for an effective coalition between provider organizations, funders, and advocates. ADDP’s record during the past year illustrates achievement of key goals, as well as successful responses to budget developments, fiscal surprises, and policy implementation.
