Engineering Matrix

What Engineering Matrix does

Engineering Matrix is a privately held, veteran-owned consulting engineering firm headquartered in St. Petersburg, Florida, founded in 1985 by Stanley P. Newton, P.E. The firm provides multi-discipline engineering design and consulting services — Mechanical, Electrical, Plumbing, Fire Protection (M/E/P/FP), plus Technology, Security, Energy, Controls, Construction Administration, Due Diligence studies, and Sustainability/LEED design — delivered as a unified in-house portfolio spanning schematic design through project close-out. Underlying technical capabilities include conventional HVAC (chillers, DX equipment, geothermal, thermal storage, energy recovery), electrical distribution and fire alarm/sprinkler design, low-voltage communications and security systems, and indoor air quality engineering with UVC decontamination and enhanced filtration.

The firm's business model is professional services consulting billed on a per-project basis, sold directly to clients with no channel partners. Go-to-market is relationship-led, with the firm stating that 90% of recent projects originate from repeat clients and 600+ clients have been served across 3,500+ completed projects over 40+ years. Customer segments are diversified across Florida government (county, city, municipal, judicial, and emergency services facilities), educational institutions (K-12 through higher education and libraries), and commercial/private sector clients including healthcare, warehouses, multifamily, religious, and historical buildings. Marketing is primarily website-based, emphasizing credentials, project portfolio, and the firm's Certified Veteran-Owned Business and Small Local Business Enterprise designations, which confer procurement preference on Florida public-sector RFPs.

Engineering Matrix is staffed by approximately 25 full-time employees, including 8 Professional Engineers, 4 LEED APs, a Physical Security Professional, a Certified Commissioning Authority, and a Registered Communications Distribution Designer. The firm is led by CEO Stanley P. Newton, P.E. (founder), President and Principal-In-Charge Gregory F. Bowen, P.E. (36+ years tenure), and Principal/VP Anita K. Crosby, RCDD (40+ years tenure). Operating geography is restricted to the State of Florida, with a primary focus on the Tampa Bay area; no subsidiaries, parent company, or external funding rounds are disclosed.
