What axiom engineering group does

Axiom Engineering Group, PLLC is a private, Montana-incorporated engineering firm headquartered in Missoula that delivers integrated SMEP (Structural, Mechanical, Electrical, and Plumbing) engineering across the Western United States. The firm complements its core structural and MEP practice with three adjacent service lines: Technology Engineering, LEED & Sustainability consulting, and Commissioning & Forensics. It operates four offices spanning Montana (Missoula HQ), Utah (Salt Lake City and St. George), and California (San Diego), and serves a project portfolio spanning luxury residential, commercial, institutional, and hospitality clients, with named engagements including Montana State University, Simms Fishing, the Montana Museum, Missoula County, and Rocky Mountain Gardens. The firm runs an active thought-leadership footprint, publishing 69+ articles, a newsletter, a podcast, and editorial features such as a Mountain Living Magazine piece.

Technically, the firm works in 3D Building Information Modeling (BIM) for multi-discipline design coordination and clash detection, with specialized expertise in geothermal system design and LEED certification pathways. The delivery model is project-based professional services, with fees tied to scope, complexity, and construction value, and the go-to-market is anchored on long-term relationships with named architectural partners (JLF Architects, A&E Design) and construction counterparties (Big-D Construction). Leadership comprises CEO John Melvin, PE (20+ years of engineering experience), COO Isabelle Markert, and Studio Directors Tristan Dunlap and Ormond Allred. The firm shows no external funding, M&A, or investor disclosures in the available data, consistent with an independent, bootstrapped professional services business.

The firm is mid-sized (estimated ~20 professionals across four offices), privately held under Montana law, and is actively hiring senior licensed engineers across mechanical, structural, and electrical disciplines, signaling capacity-led growth rather than capital-driven scaling.
