The Power of the Broker: A Mighty Role

Unlike agents, brokers are like the Robin Hoods of the insurance world. They’re all about you, the buyer, making sure your interests are front and center.

Acquisitions and Big Moves: A Look Back

Hold on tight, because the insurance brokerage industry has been one roller coaster ride of acquisitions since 2017. Picture this: USI Holdings swooping in like a hawk and snagging various insurance operations from Wells Fargo Insurance Services back in December 2017. They grabbed Wells Fargo’s commercial insurance brokerage and consulting, employee benefits, and property/casualty national practices. And that’s just the tip of the iceberg!

Marsh’s Mega Merger: A Global Affair

Fast forward to April 2019, and guess who’s making headlines? Marsh, that’s who! They pulled off the acquisition of Jardine Insurance Brokers, a multinational giant hailing from London. And guess what? According to the folks at Mercer, a Marsh subsidiary, this dynamic duo will have their fingers in pies across more than 130 countries. Talk about going big!
