Oak-Leyden Developmental Services

What Oak-Leyden Developmental Services does

Oak-Leyden Developmental Services is a private nonprofit organization (EIN #23-7380622) headquartered at 411 Chicago Ave, Oak Park, Illinois, that has operated continuously since 1956 serving people with intellectual and developmental disabilities (I/DD). The organization delivers three core program tracks: Children's Services (Early Intervention, Evaluations & Screenings, Therapy Services, and School Age Speech Services), Adult Services (Community Living Services/CILA residential arrangements, Lifelong Learning Centers, and a Supported Employment Program), and Family & Guardian Support (Connecting With Families, Guardian Resources, and Community Resources). It also operates a HIPAA- and FERPA-compliant Live Video Visits telehealth offering via Zoom for Early Intervention consultations.

The business model is a hybrid of fee-for-service delivery (likely reimbursed through Illinois Medicaid/DDD waivers, Early Intervention state funding, and insurance for clinical and residential services) and charitable fundraising. Pricing is not publicly disclosed; the organization explicitly identifies donations and fundraising event proceeds — including the 8th Annual Bankers Charity Golf Classic organized by partner Willing to Hunt — as material revenue supporting program participants. The go-to-market is direct service delivery through a single Oak Park facility plus community-based residential and employment placements within Illinois, supplemented by referral relationships with healthcare providers, schools, and community organizations and awareness-building via website and social channels (Facebook, Instagram, YouTube, LinkedIn).

There is no proprietary technology platform; service delivery relies on standard clinical and telehealth tooling (Zoom). The organization holds no disclosed patents or trademarks, has no subsidiaries, no parent company, no funding rounds, and no disclosed M&A activity. It maintains compliance posture under HIPAA and FERPA for its children's services. Public annual reports (2021 and 2022) are posted on the website but financials were not provided in the source data.
