Holding handsCoordinated Youth & Human Services (CYHS) is a non-profit social service agency serving Granite City, Madison, Venice, and the surrounding communities in southwestern Illinois. CYHS was founded in 1944 in direct response to the need for delinquency services in Granite City. The agency's original name was Coordinated Youth Services. That name was changed to include Human Services when diverse programs were added which extended beyond youth programs. As the needs of the community have changed over the years, so have the programs and services provided by CYHS.

Education of at-risk students has been a cornerstone of CYHS since its inception. The Educational Enhancement Program (EEP) was established in 1991. It offers individualized educational plans for special needs students and their families.

The Women, Infants and Children (WIC) program has been serving all of Madison County since 1974 with nutrition education and breastfeeding support. Family Case Management (FCM) was added to CYHS in 2000 and is a companion program to WIC to better serve these families. In 2001, Healthy Families Illinois (HFI) started, with an emphasis on first-time parents.

The Madison County AIDS Program (MadCAP) was established in 1986 to prevent the spread of HIV and respond to the needs of people and families affected by HIV. Case management services assist HIV positive clients, while counseling, testing, and educational services have been added to reduce the risk and spread of the disease.

As CYHS has responded to the community's needs, the facilities to support these services have changed over the years. In November 1993, the agency moved to its current building on Madison Avenue, where all the Granite City programs were under one roof. As the programs expanded, so did the need for additional space.  The educational programs were able to lease space from the Granite City School District at Lake School starting in 2000. The educational programs moved in October 2007 to River's Edge with the opening of a new 19,500 square foot building specifically designed to serve the student population CYHS serves. A WIC/FCM clinic opened in Wood River at the Madison County Health Department to better serve clients in that portion of Madison County.
