Certerra RMA Group has acquired Testing Engineers, a materials testing laboratory based in San Leandro, CA. Terms of the deal were not disclosed.

Founded in 1954, Testing Engineers operates one of the most advanced laboratory facilities in Northern California. The firm provides testing and inspection services for code compliance and quality assurance. It is particularly recognized for its metallurgy and materials testing capabilities, including analysis of structural steel, bolts, and fasteners.

The deal strengthens Certerra’s technical depth in Northern California and expands its metallurgy and materials engineering capabilities across its national platform. The added capabilities will support clients in the Bay Area and provide resources that can be leveraged across Certerra’s national network.

“This acquisition represents another important step in executing our growth strategy and strengthening our position as the partner of choice for testing, inspection, and certification services in the earth sciences and materials engineering,” stated Certerra CEO Ed Lyon.

Testing Engineers will merge into Certerra’s existing California operations.

Since 2001, Certerra has acquired more than 20 businesses to build a national platform. The company employs more than 1,800 engineers, technicians, and scientists across more than 65 offices and laboratory facilities.

Certerra is a portfolio company of OceanSound Partners.
