Our Purpose
We listen to, respect and support our customers so that children can receive the emotional and financial support they need to thrive.

The Contra Costa County Department of Child Support Services (DCSS) supports children’s futures, assisting parents and guardians by establishing, collecting, and distributing child and medical support for minors.  Our work is an important part of California’s effort to nurture and protect children and to help them and their families achieve self-sufficiency.
