Technical Professionals Group

What Technical Professionals Group does

Technical Professionals Group (TPG) is a privately held, family-owned B2B automotive testing and development services firm founded in 1950 with roots in Detroit engineering. The company provides managed program services covering vehicle validation, durability testing, mileage accumulation, ADAS data collection, facility management, technical workforce sourcing, and driver training/certification (including the SAE J3300 standard and FMCSA-approved CDL training through its sub-brand THE ACADEMY). TPG serves enterprise customers across automotive OEM, tire manufacturing, heavy duty truck, motorcycle, agricultural equipment, mechanized equipment, and ADAS/autonomous vehicle development sectors.

TPG operates two strategically located owned test centers — the Southwest Test Center in Phoenix's east valley (a 5-acre hot weather durability facility) and the Southeast Test Center in the Greenville-Spartanburg corridor — and deploys embedded technical teams at client engineering centers, R&D facilities, and proving grounds across North America. Notable technical assets include the first Examiner status for the SAE J3300 driver certification standard (in partnership with Eaton Corp), exclusive membership in the International Committee for Proving Ground Safety (ICPGS), and FMCSA-approved Entry Level Driver Training status. The company employs 251-500 people with executive leadership entirely from the Bamber family (CEO Rosemary Bamber, President Chris Bamber, VP/CFO Steve Bamber, VP HR Brock Bamber).

TPG generates revenue through quote-based, project-by-project or managed program contracts with enterprise clients, supplemented by professional services fees for technical workforce placement and driver certification. The company does not publicly disclose pricing. Its go-to-market is sales-led and relationship-based, leveraging long-tenured enterprise relationships (some exceeding 20 years), case study demonstrations, and direct inquiry through its website, with no evidence of digital marketing, channel partnerships, or reseller distribution.
