What Technical Environmental Services does

Technical Environmental Services, Inc. (TES) is a privately held, Louisiana-headquartered environmental, engineering, health and safety (EH&S) consulting firm founded in 1984 and operating across the United States. The firm provides four core service divisions — Industrial Hygiene, Safety Consulting, Environmental Solutions, and Engineering Services — augmented by Industrial Staffing, Industrial Turnaround Support, and Expert Witness offerings. Delivery is executed by a team of Certified Industrial Hygienists (CIH), Certified Safety Professionals (CSP), and professional engineers via onsite safety professionals stationed at client facilities and project-based consulting engagements. The proprietary myIH software platform standardizes industrial hygiene data management across engagements, providing structured exposure and monitoring records for client decision-making.

The firm’s primary customer verticals are petrochemical and energy, manufacturing, healthcare, government (federal, state, parish), and industrial contractors (shipyards, refineries, terminals). Revenue is generated through B2B professional services engagements on a quote-based pricing model, with no published rate cards. Go-to-market is sales-led and direct, supported by a marketing footprint that includes the company website and organic social channels (LinkedIn, Facebook, Instagram). The firm maintains a regional Gulf Coast office footprint in Marrero, LA (headquarters), Port Arthur, TX, and Baton Rouge, LA.

Ownership is private with no external investor or parent-company disclosure; leadership is anchored by President & CEO Chris Robertson (MSPH, CIH, CSP), COO Stephen Stamm (CSP), CFO Noel Pooley, and IH Services Leader Cullen Whitaker (PE, CIH, CSP). Strategic direction in 2025 has been shaped by selection into the Blue Wave International Supplier Development Program alongside Woodside Energy, culminating in the Platinum Badge award and positioning TES for major LNG and energy sector project work.
