Rimkus Consulting Group

In 1983, chemical engineer Robert E. Rimkus started a small consulting company from his Houston home. He identified a crucial gap in the market: the need for independent, scientific analysis in resolving insurance claims and legal disputes. Operating as R.E. Rimkus and Associates, he founded a business focused on forensic engineering—investigating failures and accidents to determine the root cause. The company was incorporated as Rimkus Consulting Group in 1987, laying the groundwork for future expansion. The firm's trajectory was one of steady, organic growth, building a reputation for excellence with insurance companies, law firms, and corporations. A significant transition occurred in 1995 after the passing of Bob Rimkus, when leadership was transferred to a team including S. Frank Culberson, Gary W. Markham, and Ralph S. Graham, who continued the founder's vision. The playbook shifted significantly in the late 2010s. In 2019, Rimkus accepted its first outside capital, a minority investment from private equity firm Century Equity Partners. This infusion was a catalyst, enabling the company to accelerate its growth strategy. What followed was a prolific period of acquisitions, with Rimkus making 15 strategic purchases since 2020. This buying spree dramatically expanded its geographic footprint and service lines. A new chapter began in February 2024 when the company received a major strategic growth investment from another private equity firm, HGGC. With Century Equity Partners rolling its equity into the deal, the move signaled a doubling-down on the acquisition-led growth strategy. Today, Rimkus operates from over 110 offices globally, a testament to its transformation from a solo consultancy into a major international player in the engineering and technical consulting world.
