What Challenge Unlimited does

Challenge Unlimited, Inc. is an Alton, Illinois-based nonprofit social enterprise founded in 1959 (originally as Specialized Services, Inc.) that employs approximately 900 workers — about 600 of whom are individuals with disabilities and 71 are veterans — across seven U.S. states (Illinois, Missouri, Ohio, Wisconsin, Mississippi, South Carolina, and Texas). The organization operates as an authorized AbilityOne Program partner and CARF-accredited Community Rehabilitation Program (CRP) provider, delivering a diversified portfolio of business services including environmental/custodial/janitorial services, facility support, grounds and landscaping, food service, warehousing/packaging/fulfillment, information technology, contact center operations, and contingent staffing. Its primary customers are federal and state government agencies — including the U.S. Air Force, U.S. Army, GSA, USDA, CMS (Medicare Jurisdiction F & 8), and as an approved AbilityOne subcontractor on NASA SEWP VI — supplemented by commercial accounts in packaging and food service routed through its subsidiary Project CU, Inc.

Revenue is generated through four streams: government contracts under AbilityOne and related vehicles, commercial business contracts for facilities management and production services, contingent staffing through AOS Staffing, and a smaller mix of charitable donations (e.g., Give STL Day) and grants (e.g., a $100,000 ACT grant for transportation services). The organization pursues go-to-market through direct federal contracting, SourceAmerica network participation, Illinois Department of Labor Registered Apprenticeship partnership, and community-based referral channels. Wholly-owned operating affiliates include Residential Options, Inc. (CILA and ICF/DD residential services in Illinois-Metro East), Project CU, Inc. (St. Louis extended employment services), AOS Staffing, and Alpha Industries. Leadership is provided by President and CEO Charlotte Hammond (since 2016) with a board chaired by Joni Lombardo and a senior team including a Brigadier General as EVP of Operations, reflecting the organization's deep alignment with federal and military contracting channels.
