ADDP Legislative Luncheon at the Massachusetts State House

ADDP works on behalf of developmental/intellectual disability and brain injury services providers. Support of ADDP has helped ensure disability issues are a priority in the Legislature. Through our advocacy, and the amazing work of our members, we have gained respect from members of both parties, both chambers of the legislature and by members of the executive branch.

Our history of protecting our sector is well known both in Massachusetts and nationally. During the Great Recession, while most states were cutting their programs to the bone, Massachusetts developmental disability programs were protected. Any threats to cut programs were defeated in the legislature or reversed by the executive branch. As a member of ADDP, you receive numerous benefits, including:
