Marsh McLennan Agency Bolsters California Presence with Acquisition of Olympic Insurance Agency
WHITE PLAINS, NY – August 5, 2025 – Marsh McLennan Agency (MMA), a subsidiary of global risk advisory leader Marsh, announced on August 1, 2025, the acquisition of Olympic Insurance Agency, a Simi Valley, California-based independent firm, as part of its ongoing U.S. expansion strategy. Financial terms of the deal were not disclosed. The acquisition enhances MMA’s expertise in real estate-driven insurance solutions, particularly for investors, property managers, and manufacturing businesses in Southern California.
Founded in 1947, Olympic Insurance Agency specializes in business insurance, employee benefits, and personal asset protection, with a strong focus on serving real estate and manufacturing sectors. All Olympic employees, including principals Don and Bob Barberie, will remain with the company, continuing operations from the existing Simi Valley office. “We have admired the team at Olympic, and Don and Bob’s collaborative leadership, for many years,” said Chris Williams, CEO of MMA’s West region. “Their real estate expertise and dedication to innovation will bring new perspectives to our clients.”
Don Barberie emphasized the alignment with MMA, stating, “Delivering exceptional service and proactive risk management solutions has always been at the core of our mission. MMA enhances our capabilities to better serve our clients.” Bob Barberie added that the partnership allows Olympic to “elevate client outcomes” while supporting the team’s professional growth.
This acquisition follows MMA’s aggressive M&A strategy, including the $7.75 billion purchase of McGriff Insurance Services in November 2024, which added 3,500 employees and $1.3 billion in revenue, and smaller deals like Perkins Insurance Agencies in Texas (June 2024) and Excel Insurance in South Florida (July 2024). MMA’s parent company, Marsh McLennan, reported a robust $7 billion in revenue for Q2 2025, up 12% year-over-year, underscoring the financial strength driving its expansion.
The move strengthens MMA’s West Coast footprint, aligning with its broader mission to provide tailored business insurance, employee health and benefits, retirement, and private client solutions across the U.S. and Canada. As AI-driven risks, such as algorithmic errors and autonomous vehicle liabilities, fuel demand for specialized insurance, MMA’s acquisition of Olympic positions it to capitalize on emerging opportunities in the $4.8 billion AI insurance market projected for 2032.
