Irvine Insurance Brokerage Acquired

NuWest, headed by Chief Executive Chuck Rosenberger, has about $2.4 million in annual revenue. It’s expected to fold into Marsh & McLennan Agency’s MMA West operations, which were established early this year when the agency acquired Barney & Barney LLC.

San Diego-based Barney & Barney has an office in Aliso Viejo.

Marsh & McLennan Agency is part of Marsh & McLennan Companies Inc., a New York-based global professional services firm. The publicly traded parent company had about $12 billion in revenue last year and has about $30 billion in market capitalization.
