Developmental Disabilities Institute (DDI) has been assisting individuals with developmental disabilities and their families on Long Island for almost 60 years.
During that time, we have evolved and grown, serving larger numbers of people and expanding the types of supports and services we provide.
Our evolution has always been focused on delivering on our mission to help children and adults with autism and other developmental disabilities experience growth and fulfillment.
