DDI serves more children and adults with autism than any other service provider on Long Island.
    
    Thanks to the advanced programs and comprehensive facilities found at DDI, there is hope and excitement for individuals and their families to help them fully realize their potential. We understand that education is the gateway to living independently, and starting early is the key. Every small success helps to erase some of the uncertainty that was once part of everyday life. With locations in both Nassau and Suffolk Counties, New York, DDI is fulfilling a vital and unique need for children and adults with autism and other developmental disabilities and the communities they live in.
