CSS also collaborated with state and local agencies responsible for children. CSS began providing DDA-funded Family Support Services in 1995, which assisted families with needed supports to maintain in their homes their children with severe developmental disabilities. Children's services provided included after-school programs, summer camps, environmental accommodations, specialized equipment and in-home support. The Governor’s Office for Children, Youth, and Families, working through the Local Coordinating Council, facilitated collaboration among state agencies responsible for children with intensive needs who were in out-of-state placements or at risk for such placements. In 1995, as a provider, CSS worked closely with the OCYF, other lead agencies, the Maryland State Department of Education, and the DHR in the State’s locally administered Systems Reform Initiative to provide wraparound services to Montgomery County children and their families in order to return and divert out-of-state placements. CSS partnered with Montgomery County Public Schools (MCPS) and the State-established Montgomery County Collaboration Council for Children, Youth, and Families to develop creative models of service, including job coaching, residential support, community instruction, and behavior management, for students with severely challenging behaviors. CSS’ staff worked with the disability services unit of the Montgomery County Department of Health and Human Services to provide in-home supports, recreational programs and transition services to youth with severe developmental disabilities. In 2005, CSS became an approved provider under the Maryland Medicaid Home and Community-Based Services Waiver Program for Children with Autism Spectrum Disorder.

CSS' growth has been spurred by its commitment to meeting the needs of the surrounding community. As a result, CSS has become one of the leading providers of specialized care to individuals with autism and other complex developmental delays in Montgomery County.
