2025 Rescheduled Walk; fall-themed flyer

2025 Walk is Rescheduled!

We’re excited to announce that our annual walk has been rescheduled for Saturday, November 22, 2025, at the Suffolk Credit Union Arena on Suffolk County Community College’s Brentwood campus! This state-of-the-art facility will be a fantastic venue.

The new date gives us all more time to support our teams and make this a record-breaking event. Just days before Thanksgiving, we'll come together to walk with a purpose and turn gratitude into action. We can't wait to see you there!

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.

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.

Inclusion

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

Strategic Plan

With input from internal and external stakeholders, our 2024-2026 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.
