Strategic Plan

Developmental Disabilities Institute (DDI) has been assisting individuals with developmental disabilities and their families on Long Island for more than 50 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.

Why DDI?

"Everyone involved over in the Plainview Day Hab did an incredible job tending to every possible problem that might arise for her, and was prepared and ready to help Lauren feel safe and secure."

The day hab coordinator, Michelle and the manager, Dora, go above and beyond in their goal to treat each and every individual coming there with respect and consideration of their particular needs. It has been a very good transition for my daughter and I know that could not have been accomplished without the constant consideration of the whole team working there. ~The Valentino Family

"From the very first day, Andrew Braithwaite and his staff treated our students and their parents with the utmost care and respect."

Three Village Central School District has been contracting transportation through Developmental Disabilities Institute since January, 2011. All IEP mandated accommodations are put into place immediately. No request is too large or issue too small. I can honestly say that I have never received one complaint from a parent in the past six years. I look forward to working with them for many years to come. Dawn Mason, Executive Director

"Our family is incredibly thankful for the excellent services our daughter has received through DDI."

She had so many wonderful, caring teachers over the years and gained many skills. We are now fortunate again that she is attending a wonderful day hab program in Plainview. She has had the opportunity through this program to be integrated into community events and activities. We are also very pleased with the adult residential program where she lives. We are able to see her continue to gain independent skills due to her setting. Our daughter is always happy to come to our home and is happy to return to her DDI home.   We are thankful for the wonderful team at DDI.   ~Marcy Klein
