What ABA does

ABA of Illinois, LLC is a privately held applied behavior analysis (ABA) service provider founded in 2009 by Karen Harper and headquartered in Darien, Illinois. The company delivers clinical and consultative behavior analysis services to adults with disabilities and their families across natural environments including homes, day programs, vocational programs, group homes, and community living arrangements. Its clinical methodology centers on functional behavior assessments, customized person-centered programming, proprietary data collection systems with continuous progress monitoring, and positive behavior change strategies grounded in ABA principles.

The company operates three core service lines: direct behavior services for adult clients, professional training and workshops (including professional crisis management, BCBA/BCaBA supervision, RBT training, and CEUs), and staff and caregiver training. Underlying technology is clinical rather than software-based, relying on BCBA expertise, manual data collection frameworks, and individualized program design. The company employs over 55 behavior staff supporting more than 1,000 clients and 25 partner agencies statewide, with billing conducted through insurance (Blue Cross Blue Shield of Illinois) and free consultations offered at intake.

Revenue is generated almost entirely through professional services fees. Customer acquisition is driven by a referral network of 25 partner agencies, direct intake through the company website and contact channels, and an active hiring funnel (via Indeed) that doubles as a brand presence in the BCBA labor market. Strategic partnerships with Purdue Global University (online BCBA certification pathway with 14% tuition discount) and Southern New Hampshire University (10% discount on 200+ programs for employees and family members) function as talent pipeline and retention mechanisms. In April 2026, the company announced its first geographic expansion outside Illinois, into Sugar Land, Texas, signaling an early multi-state posture. No external funding rounds, M&A activity, or institutional investment are disclosed.
