Occupational Care Services

What Occupational Care Services does

Occupational Care Services (OCS) is a Michigan-based, 100% woman-owned occupational health company that delivers OSHA, FMCSA, FAA, and DOT compliance testing, conservative-care injury treatment, and workplace safety training to employers across construction, manufacturing, transportation/logistics, energy, aviation, healthcare, and municipal/public safety. The company was incorporated in 2015 and operates atop 30-plus years of accumulated occupational healthcare experience held by its leadership team led by CEO Nicole Adams-Gibson. Service reach combines six Michigan clinic and network-partner locations (Livonia HQ, Ann Arbor, Dearborn, Lincoln Park, Taylor, Pontiac) with 24/7/365 mobile field deployments nationwide, anchored by a National TPA Program that extends single-account access to 3,000+ partner clinics across the United States.

The service portfolio spans respirator fit testing, silica and asbestos/hazmat physicals, boothless audiometry, FMCSA-compliant DOT physicals, SAMHSA-certified drug and alcohol testing, workplace vaccinations, NFPA-compliant firefighter physicals, and MCOLES law enforcement exams, with training and certification delivered both onsite (HSI First Aid/CPR/AED) and through an online portal of 2,000+ OSHA courses. Technical differentiators include portable boothless audiometry hardware that completes pure-tone hearing tests in 5–10 minutes per employee without a soundproof booth, the OneTest multi-cancer early detection (MCED) blood screen integrating FDA-approved biomarkers with AI for 28+ cancer types, a nationwide Tele-Triage Program routing injured workers to OCS providers in real time, and a “conservative care” injury protocol credited with an 82% reduction in OSHA recordability in 2025. Distribution is direct-sales-led via field outreach, employer authorization workflows, industry-association participation (CAM, AGC, NAWIC, NAOHP, Michigan Safety Conference, Michigan Manufacturing Association), and a DISA Global Solutions drug-and-alcohol testing partnership.

Revenue is generated through four professional/managed services streams: walk-in and appointment-based clinic services (DOT physicals, drug screening, injury care, vaccinations), 24/7 mobile onsite deployments to employer worksites, TPA-managed nationwide coordination and consolidated billing, and workplace training and certification programs priced by class size and location with volume discounts. Pricing is quote-based and not publicly disclosed; the firm’s 100% woman-owned certification qualifies it for federal contracting preferences and corporate supplier-diversity programs, opening a distinct bid channel that complements its commercial sales motion.
