The firm delivers on-site occupational and environmental health services — including asbestos inspection and air monitoring, silica compliance auditing, indoor air quality and LEED testing, hazardous waste site monitoring, mold and moisture assessments, Legionella risk management, construction safety, and biosafety / radiation safety support — primarily to commercial, institutional, and higher education clients across the New England region. Core delivery is grounded in licensed talent: multiple Certified Industrial Hygienists (CIH) and Certified Safety Professionals (CSP), a licensed in-house asbestos laboratory, and over a dozen licensed project monitors, designers, and inspectors, with 75+ years of combined consulting experience among principal staff. Services are sold on an hourly or project-rate basis through direct sales and relationship-driven channels, with quotes tailored per engagement and final invoices bundling on-site labor, report generation, sample analysis, lab fees, and third-party equipment. Customer concentration is weighted toward higher education (Harvard, Boston College, Wellesley, Brandeis) and healthcare (Dana Farber, Brigham and Women's), supplemented by construction (Suffolk, Shawmut), insurance (Liberty Mutual), real estate (CBRE), and government accounts. Revenue streams are entirely professional-services, with no software, platform, or AI component disclosed. The company operates under the legal name Environmental Health, Inc., is founder-led (Philip G. Terrell, CEO/CIH/CSP), is independently owned with no outside investment, and is licensed in Massachusetts, Rhode Island, and New Hampshire.
