Who we are

Keystone Alliance is a family of nonprofits that all share a powerful mission, to empower individuals with intellectual and developmental disabilities to live, work, recreate, and participate fully in their community.  This mission is at the heart of everything we strive to accomplish. It is the yardstick by which we measure success. We believe that nonprofits can achieve better outcomes for the people they serve through collaboration and partnership. 

Our member organizations serve more than 1,400 adults and children with intellectual and developmental disabilities annually throughout the Chicagoland area.  Keystone supports this important work with highly flexible administrative and consultative services. We offer a comprehensive set of tools for nonprofits to grow mission impact, foster long-term mission sustainability and create innovative program models.
