What Health Science Associates does

Health Science Associates (HSA) is a California-based industrial hygiene and environmental consulting firm founded in 1970 and headquartered in Los Alamitos. The firm delivers a full-service portfolio of occupational and environmental health and safety services, including Industrial Hygiene & Safety assessments, Indoor Air Quality and Mold/Fungi investigations, Asbestos and Lead-Based Paint surveys, Safety and Health Management planning, Chemical/Biological Exposure Assessments, Heat Illness Prevention Services, Cal/OSHA- and CDPH-certified training programs, and Expert Witness/Litigation Support. Service delivery is grounded in conventional industrial hygiene methodology — air monitoring, noise surveys, polarized light microscopy, sample analysis, and compliance review — executed by a small team of Certified Industrial Hygienists, Certified Safety Professionals, Certified Asbestos Consultants, and CDPH Inspector/Assessor/Project Monitors.

The firm operates on a fee-for-service, project-based consulting model. Engagement scope ranges from one-day assessments to large-scale long-term renovation monitoring programs, with pricing provided on a quote basis tied to scope and complexity (pricing is not publicly disclosed). HSA does not use resellers or distributors; all work is delivered directly by its staff at client facilities across Southern California and neighboring states. Its go-to-market is sales-led and reputation-driven: clients are acquired through direct phone/email/website inquiry, referrals from satisfied customers and enforcement agencies, and a free-consultation offer supported by client testimonials, blog content, email newsletters (via Constant Contact), and active participation in AIHA, ASSP, Cal/OSHA, CIHC, and OCAIHA.

Health Science Associates serves five identified segments — Commercial & Industrial (primary), Construction & Renovation, Government & Education, Residential, and Legal — with named client work for the City of Anaheim, City/County of San Francisco, Cal-Trans, Los Angeles County Child Care offices, and Ocean View School District. The company is privately held under founder/CEO Howard B. Spielman and President Joel I. Berman, classified as a Certified Small Business Enterprise in California, and reports 11-50 employees. No external funding, acquisitions, or ownership changes are documented across its 55-year history, indicating long-term founder/management control and a stable, regionally focused operating model.
