Oak-Leyden Developmental Services, Inc.

Oak-Leyden Developmental Services, Inc., a nonprofit organization based in Oak Park, Illinois, operates exclusively as a federal grant sub-recipient, delivering community health and paratransit services through grants from the Department of Health and Human Services Centers for Disease Control and Prevention and administered by Cook County Department of Public Health.

The organization's federal footprint is limited to three sub-grant awards totaling $346 thousand obligated dollars across a two-year window. Oak-Leyden has not served as a federal contract prime or IDV holder and does not compete for direct federal contracts. Work to date centers on two paratransit vehicle procurement and deployment awards (April 2025) and one community health worker initiative award under the Suburban Cook County Community Health Worker Initiative administered through Cook County Department of Public Health (July 2023). The organization serves a single federal customer agency — the CDC — making it a highly specialized sub-recipient for suburban Cook County public health infrastructure and transit support.

Activity has been sporadic: one award in 2023, then a two-year gap before two awards in April 2025. The organization lacks presence on federal IDVs, GWACs, or agency-wide BPAs and does not maintain a contracting footprint independent of grant sub-award relationships. Oak-Leyden's role is confined to implementation of grant-funded initiatives within its geographic area rather than prime contractor or vehicle participation, positioning it as a local service delivery organization within Cook County's federal health and human services grant ecosystem.
