Community Partners

With sites and residences located throughout Long Island, DDI has had the opportunity to partner with many organizations that help drive our mission forward. 
Below is a list of our affiliations and employers of the people we serve.  They each help ensure that the children and adults with autism and other developmental disabilities supported at DDI experience personal growth and fulfillment. We accomplish this mission by developing person-centered plans that focus on the individual goals and interests of each person.
Whether you are interested in research, higher education, employment opportunities or have an idea or connection you want to share, we would love to hear from you. Join us in making a difference in people’s lives, and email us at [email protected] today.

DDI is committed to diversity and inclusion for ALL people. We are a family of unique individuals bound by a common mission.

Strategic Plan

With input from internal and external stakeholders, our 2022-2024 Strategic Plan serves as our roadmap to operational and program excellence.
DDI uses data to more effectively inform our decision-making and improve how we measure our progress as an organization and with each individual we serve; how we recruit, retain, develop and continue to show our appreciation to the people who constitute our workforce, the backbone of our organization; how we commit to actions to become more diverse, equitable and inclusive; and how we more effectively coordinate the advocacy needed with legislators and policymakers to bring about positive reform.

Why DDI?

Robert's team goes above and beyond the call of duty.

The classroom teacher, behavior specialist and the teaching assistants in his classroom have been nothing short of amazing. They are so wonderful in communicating with us and they share in the joys and excitement we have regarding our son's accomplishments.
~Siobhan Domingo, Early Childhood Parent
