Marsh & McLennan Agency acquired Security Insurance Services in 2012. That agency, which was founded in 1983, established MMA's New Berlin and Appleton, Wisconsin offices. 

Its professional insurance advisors, together with its exceptional service team, partners with clients to provide expert advice to help navigate through today’s business climate. The local teams put into place a strategic risk management process that includes: an in-depth analysis of a client’s business; help identifying, preventing and monitoring risks; a full-range of customized solutions. The Milwaukee operations are committed to being specialists in both the products that it represents and the industries it serves.

MMA provides the best-in-class resources available to keep its clients informed, educated and trained, helping to improve business operations and profitability.
