Multiplicity Therapeutic Services

What Multiplicity Therapeutic Services does

Multiplicity Therapeutic Services, Inc. (MTS) is a private, founder-owned provider of Applied Behavior Analysis (ABA) and related therapeutic services for children and adults with autism, developmental disabilities, and intellectual disabilities. Founded by Charles Chojnacki — a clinician with 30+ years of experience in the I/DD field — the company is headquartered in Arcata, California and operates regional offices in Crescent City, Eureka, Ukiah, and Cotati, serving Del Norte, Humboldt, Mendocino, Lake, Sonoma, and Marin counties. Service delivery is conducted 1:1 by Behavior Consultants (degreeed ABA clinicians, $4,500-$5,200/month salary range) and part-time Behavior Aides ($18-$23/hour) in clients' homes, schools, and community settings.

The company's service portfolio spans the full I/DD continuum: functional assessments, consultation, intensive behavior support, school contracts, private services, supported living, residential facility support, independent living skills, and day/vocation programs. The core methodology is ABA, delivered by BCBAs and a clinical team with backgrounds in Psychology, Social Work, Education, and Applied Behavior Analysis. MTS positions itself around a person-centered approach that explicitly incorporates cultural and social diversity into treatment planning.

Commercially, MTS operates as a professional-services referral partner rather than a payor-direct practice. Revenue is generated through service authorizations issued by California's Regional Center system (Northbay Regional Center and Redwood Coast Regional Center) and through the Partnership of California managed-care health plan. The company has 11-50 employees, no disclosed funding or institutional investors, and an executive leadership team led by Executive Director Kier Flicker (MA, BCBA), CFO Maria Baron, Operations Director Haley French (MBA), Associate Director J. Steven Porter (MA), and Clinical Supervision lead Rochelle Henderson (Psy.D.). No proprietary technology platform, software product, or AI capability is disclosed; operations are entirely service-based.
