Developmental Disabilities Institute
UPDATED: December 7, 2021
Developmental Disabilities Institute (DDI) was founded in 1961 to address the special education needs of children with autism and other developmental disabilities and provide therapeutic intervention.
Today, DDI is a dynamic, non-profit, multi-site agency, each day serving hundreds of children and adults with autism and other developmental disabilities, providing educational, residential, habilitative, vocational, transportation, and service coordination support to the Long Island community.
DDI's educational, residential, day, and vocational supports are as diverse as the people we serve. Through more than 60 years of sustained effort, DDI has grown substantially.
Our agency recognizes the unique needs of each person for whom we care and maintains the highest standards of teaching for our children, adults, and families, as well as training for our staff. We pride ourselves on utilizing research-based methods across all agency programs.
