Trilon Group

What Trilon Group does

Trilon Group is a Denver-based infrastructure consulting platform launched in January 2022 by Alpine Investors as a vehicle to aggregate best-in-class U.S. engineering firms. The company operates as a holding entity for 15 wholly-owned platform partners — including Waggoner Engineering (founding partner), MSG, DRMP, Alta Planning + Design, Gonzalez Companies, Wilson Engineers, Fehr Graham, HMB, Horrocks, Fuss & O'Neill, Rinker Design Associates, Talbert Bright & Ellington, Naik Consulting Group, and the newly launched Artheon (2026 merger of CME, Churchill, and Naik). Each partner firm retains its regional brand and client relationships while sharing centralized resources. Trilon serves federal, state, and local government agencies, municipalities, and enterprise infrastructure owners across five vertical service lines: Transportation, Water and Environmental, Community and Municipal Infrastructure, Energy Facilities and Utilities, and Project Delivery and Construction Management.

The platform's underlying technology stack is built around Deltek Vantagepoint, which Trilon consolidated company-wide in 2025 as the unified enterprise project management and accounting system. Beyond core ERP, Trilon has built internal people-development infrastructure including TrilonU (a learning community launched May 2024), the Trilon Scholarship Program (2024), Grow Leadership Program (2025), and Emerge program (2026). The firm's core technical value proposition is aggregation of multidisciplinary engineering expertise — transportation planning, water resource engineering, environmental compliance, municipal infrastructure design, and energy/utility consulting — delivered through 185 offices across North America with 5,750 employees as of 2025.

Trilon's business model is project-based professional services revenue, with consulting fees generated through government RFPs, municipal contracts, and enterprise infrastructure engagements. Growth has been driven primarily by an aggressive M&A program backed by Alpine Investors' commitment of up to $200 million. The company ranks #21 on the ENR Top 500 Design Firms list (up from #66 at launch) and received Morrissey Goodale's Most Prolific and Proficient Acquirer Award in 2025. Customer concentration is in the public sector (government and municipal infrastructure owners), with pricing quote-based and project-by-project rather than productized or subscription-based.
