DDI's programs span the lifespan, offering early childhood education, school-age programs, and children's residential services. For adults, the organization provides day services, residential services, vocational training, and self-direction support. Transportation services are also available to support individuals and families.
The organization's approach is grounded in evidence-based practices, including Applied Behavior Analysis (ABA), combined with creative strategies.
