A3GEO will operate as a business unit of RMA GeoScience and Dona Kelly will lead the combined group as President.

RMA is a leading provider of professional services in environmental consulting, geosciences, and materials testing and inspection for critical public and private infrastructure assets across diverse government and commercial end-markets, including transportation, healthcare, education, renewable energy, and water resources.

RMA’s team of engineers, geologists, inspectors, and technicians help infrastructure asset owners, engineering firms, and construction companies maintain compliance with strict regulatory and operating requirements through a range of geotechnical, environmental, and materials testing services. Founded in 1962, RMA is headquartered in Rancho Cucamonga, California. RMA is a portfolio company of OceanSound Partners.

Since December 2021, RMA has completed eight acquisitions, as it executes an aggressive growth strategy to build a national platform providing geotechnical engineering, environmental consulting, construction materials testing, inspection, and certification to support the development of the nation’s critical infrastructure.

OceanSound Partners is a New York-based private equity firm that pursues control investments in technology and technology-enabled services companies serving government and enterprise end-markets.

“I am thrilled to have taken this step as it will open new doors for our clients and create opportunities for our professional staff,” said Wayne Magnusen.
