What Koury Engineering does
Koury Engineering is a privately held geotechnical engineering and construction quality-assurance firm founded in 1992 and headquartered in Chino, California, with a second office in Gardena serving the Los Angeles metropolitan area. The company provides Independent Testing Laboratory and Engineer-of-Record services for residential, commercial, institutional, and infrastructure construction projects across Southern California — Los Angeles, Orange County, San Diego, and the Inland Empire — with project references spanning 60-story Downtown LA high-rises to neighborhood-school shade structures. Core service lines comprise Special Inspection (concrete, masonry, structural steel, and non-destructive testing including dye penetrant, magnetic particle, ultrasonic, visual, and radiographic methods), Geotechnical Engineering (soils testing, seismic analysis, slope stability and landslide mitigation, foundation recommendations), and Structural Test and Inspections across soils, aggregates, reinforcing steel, concrete, masonry, fireproofing, structural steel, and roofing materials.
The firm is differentiated by a stack of sector-specific regulatory credentials: Caltrans certification for highway and rail projects, Division of the State Architect (DSA) certification with over 25 years of specialized K-12 and educational facility experience, and Office of Statewide Health Planning and Development (OSHPD) certification for hospital and healthcare facility construction. Additional compliance positions include US Army certification and CCRL accreditation for the in-house materials laboratory, with engineering work verified by licensed Geotechnical Engineers registered in multiple states. The technical leadership bench includes personnel with 25-33 years of domain experience and an Engineer-of-Record who has served in that capacity on 500+ projects, supported by field inspectors sourced from the trades they inspect.
Koury's revenue model is project-based and quote-driven, with no publicly disclosed pricing, recurring SaaS-style contracts, or anchor customer relationships. Go-to-market is direct, via a request-for-proposal workflow, contact forms, and a content/blog presence on its company website. The company reports 51-100 employees and is not publicly traded, with no identified parent company, external investor, or subsidiary structure disclosed; leadership since October 2018 has been President & CEO Michele Shams, supported by SVP & COO Dave Menefee, Engineering & Technical Director Michael Carrillo, Controller Justine Cezar, CPA, and senior geotechnical engineers Jacques Roy and Armen Gaprelian.

Koury Engineering competitors and assessment
Company assessmentDirect peers
- Twining, Inc. California-based materials testing and special inspection laboratory with a similar Southern California footprint. Direct competitor in concrete, masonry, and steel inspection as well as accredited testing services.
- Earth Systems Pacific: California geotechnical engineering and inspection firm providing soils testing, materials testing, and special inspection. Closely comparable service mix and regional focus, especially in Southern California.
- BSK Associates: Geotechnical engineering and materials testing firm with strong California operations. Overlaps with Koury in geotechnical reports, foundation recommendations, and accredited lab testing for public-sector work.
- Geocon West (Geocon): California-focused geotechnical and environmental consulting firm serving commercial, residential, and public-infrastructure clients. Competes with Koury for SoCal geotechnical engineering mandates and DSA/OSHPD project work.
- Ninyo & Moore: Large California-based geotechnical, environmental, and materials testing firm with offices across Southern California. Direct peer to Koury given overlapping service lines (soils testing, special inspection, NDT) and shared regulatory certifications for public-sector work.
Broad incumbents
- Kleinfelder: National engineering, architecture, and environmental consulting firm with significant California presence in geotechnical and construction materials testing. Overlaps with Koury as a multi-discipline incumbent capable of taking mid-to-large SoCal projects.
- ECS Group of Companies: National engineering firm offering geotechnical, construction materials, and environmental testing services across the U.S. Adjacent competitor with growing California exposure, providing similar special inspection offerings.
- Terracon: National geotechnical, environmental, and materials testing firm with Southern California offices. Competes broadly for the same inspection and testing scopes, with significantly larger balance sheet and geographic reach.
Regional players
- Byer Geotechnical: California-based geotechnical engineering firm specializing in hillside and slope stability work. Comparable niche overlap with Koury's geotechnical practice, though smaller and more specialized in landslide/seismic analysis.
- Terra-Petra Environmental Engineering: Los Angeles-based geotechnical and environmental engineering firm serving Southern California real estate developers. Comparable to Koury on SoCal geotechnical scope but lighter on transportation/healthcare special inspection work.
