At MMA, Our Business Is To Be There In The Moments That Matter For Our Clients, Colleagues, And The Community.

Our story begins in 1909, when two brothers set out to insure fishing boats in the San Diego Harbor. Since then, we have grown to become one of the leading insurance brokerages in San Diego and across the US. We are passionate about insurance because it makes an impact on our beloved San Diego community in very real ways. In fact, our mission is to make a difference in the moments that matter.

With over 400 colleagues in the San Diego office alone, we provide innovative insurance solutions for our clients in the areas of business insurance, employee health and benefits, retirement services, surety, and private client services.

We are honored to support companies who are innovating within their industry. We think of ourselves as the innovator’s innovator. We do this through a model we call World Class. Local Touch. What this means for our clients is we know and care about them while also bringing them the resources typically reserved for giant firms.

With an open door culture, our colleagues drive new and creative ideas. Whether they serve formally as a member of the Marketplace & Innovation Trends Team or compete in a fun Shark Tank-like competition, our colleagues share ideas that make a difference in everything from our culture to client experience, and beyond.

Here are just a few examples of our innovative programs, tools, and resources:

  • We are committed to building a diverse and inclusive workplace. Marsh & McLennan is a National Diversity Council (NDC) corporate partner.
  • GROW (Growth & Relationships and Opportunities for Women) is a first-of-its-kind program designed to support the professional development and advancement of our women colleagues.
  • The Barney & Barney Foundation was formed to commemorate our 100-year anniversary. The foundation celebrated its 10th year in 2019 and has provided 3 million dollars to 200 California nonprofits.
