What GMU does
GMU Engineers & Geologists is a privately held, multi-disciplinary geotechnical, pavement, structural, and civil engineering firm founded in 1967 and headquartered in Rancho Santa Margarita, California. The firm provides an integrated service portfolio spanning geotechnical investigation and design, pavement engineering, structural and civil engineering, forensic engineering and expert witness work, soils and materials testing and inspection, and construction management and monitoring, with additional specialized capabilities in Ground Penetrating Radar testing, blasting consulting, and special inspections. Technical staff hold PE, GE, PG, and CEG licenses and several hold Ph.D. degrees; many field technicians are also Registered Special Inspectors, allowing GMU to self-deliver multi-disciplinary site coverage.
GMU's customer base is concentrated in Southern California and segmented across master-planned community developers (most notably a multi-phase flagship relationship with Rancho Mission Viejo), commercial and industrial developers, over 26 on-call city and county public-sector clients, water and wastewater agencies, harbor authorities, and residential developers. The firm has been recognized with multiple ASCE Project of the Year awards across 2011-2025 spanning geotechnical, structural, transportation, flood management, environmental, and sustainable engineering categories. In 2023 the firm relocated to an expanded headquarters after 26 years at its prior location, and in 2025 it executed a leadership transition moving Greg Silver to CEO Emeritus/Senior Principal.
GMU generates revenue through project-based professional engineering fees billed on a fee-for-service or contract basis, with engagement driven by direct principal relationships, on-call municipal contracts, and project-team participation on large master-planned and public infrastructure developments. Its go-to-market is entirely direct, supported by an active blog (83+ posts), LinkedIn/Facebook/X presence, and credentials from ASCE, Calgeo, SEAOC, OCWA, and the Building Industry Association. The firm holds no patents or trademarks on AI/ML technology, offers no software products or APIs, and has no disclosed external funding, operating as a closely held private firm.
