IAC was formed in 1977 in response to the horrors revealed at the Willowbrook facility. A group of 30 non-profit agencies, mostly founded and operated by parents of children with developmental disabilities, banded together in an Inter-Agency Council to work with government to design, develop and operate a new, ground-breaking service system. While excited by the prospect of creating a community-based network of residences to replace the large institutions, the Council was worried that the needs of those living at home, who had never entered an institution, would take a backseat to the court-mandated services for those leaving institutions. IAC was born from the need to meet that challenge. And IAC continues to work with non-profit agencies, families, government and legislature on the development of a service system that ensures each individual with developmental disabilities is able to realize his/her potential while being fully integrated in his/her community.
