Why Your Support Matters

We’re continuously evolving to provide innovative, person-centered supports that help the children and adults we serve to live fulfilling lives. When local leaders and our community step forward, they propel that mission in powerful ways.

This year, your gift to DDI has been generously matched up to $20,000 by the Boileroom Group.

"The staff is amazing, the facility amazing. He is loved, cared for, nurtured and protected."
