What Environmental Consultants does
Environmental Consultants, LLC is a St. Louis, Missouri-based environmental consulting firm founded in 2003 by Jeff Faust and Jim Yasitis. The company delivered testing, inspection, and consulting services across ten core practice areas spanning environmental testing, environmental inspection, industrial hygiene solutions, environmental risk planning, indoor air quality consulting, asbestos consulting, microbial consulting, lead-based paint consulting, and project management and compliance liaison services for remediation activities. The firm served five primary verticals — education, healthcare, government, industrial, and commercial — with a stated service reach across the Midwest and the broader United States. Its value proposition rested on decades of regulatory knowledge, field-experienced industrial hygienists and environmental scientists, and relationship-based trusted-advisor positioning on complex, multi-year projects addressing increasingly stringent environmental compliance, aging infrastructure, and rising environmental expenditures.
Environmental Consultants operated as a private LLC for 20 years with no disclosed external funding, pricing model, headcount, marketing channels, or distribution mechanisms; all client engagements were direct B2B consulting services delivered by the firm's technical staff. In September 2023 the firm was acquired by J.S. Held, a global consulting firm, and integrated into J.S. Held's Environmental, Health & Safety (EHS) practice, with the founders joining as directors within the larger organization. The acquisition extended J.S. Held's Midwest presence and strengthened its industrial hygiene and environmental services offering; Environmental Consultants' own standalone identity and revenue trajectory became subsumed into the parent's broader practice and are no longer reported independently.
The underlying service model is a classic professional services operation: domain experts sell time and expertise on remediation, compliance, and risk-planning engagements to facilities owners and operators facing environmental and occupational health obligations. No proprietary technology, software products, or differentiating technical platforms are disclosed; the offering is human-capital-intensive and trust-driven rather than productized.
