What CTL|Thompson does
CTL|Thompson, Inc. is a privately held engineering consulting and testing firm founded in 1971 and headquartered in Denver, Colorado. The company delivers professional engineering services across six integrated disciplines: geotechnical engineering, structural engineering, materials testing, IAS-accredited laboratory testing, environmental services, and construction observation and testing. These services are delivered to clients across commercial, residential, industrial, environmental, and infrastructure project categories throughout Colorado, Montana, and Wyoming, supported by a network of nine regional offices that enable localized engagement and rapid field response.
The firm's underlying technical capability rests on a multidisciplinary team of engineering consultants and field technicians, supplemented by an IAS-accredited laboratory that issues certified analyses of construction materials and environmental samples. Notable engagements demonstrate a portfolio that spans high-visibility institutional work (International Museum of the Baroque, U.S. Navy Diego Garcia Radomes communications facility expansion in the Indian Ocean), large-scale master-planned development (the 4,000-acre Aurora Highlands in Aurora, Colorado), and complex mountain infrastructure (the 2,100-foot vertical rise Lone Peak Tram at Big Sky Resort). Over its more than 50-year history, CTL|Thompson has completed more than 100,000 projects, building a brand reputation in the Rocky Mountain region where soil, terrain, and climate conditions reward localized expertise.
CTL|Thompson operates as a private, independent professional services firm with no disclosed parent company, subsidiaries, or institutional investor ownership. Revenue is generated through project-based, quote-priced engagements sourced via direct office consultation — a sales-led go-to-market motion targeting developers, contractors, and government agencies. The firm reaches prospects organically through LinkedIn, Facebook, YouTube, and Instagram channels, and converts inquiries at the office level into long-tail consulting and testing engagements.
