Experienced commercial real estate Broker Michael Olson has joined the brokerage team at The Grossman Cos. Inc., the Quincy-based commercial brokerage and property management firm.

Olson, a resident of Boston who earned his degree in economics finance from Bentley University, started his career with OneBeacon Insurance where he assisted with the acquisition, financing, design and build-out of the company’s 280,000 square-foot headquarters in Canton.

"Mike is a great addition to our brokerage team," said Richard McKinnon, the company’s director of brokerage services. "He brings a wealth of experience and contacts throughout Greater Boston and the South Shore, and we know he will generate opportunities with a primary focus on tenant representation."

For the last five years Olson served in various roles with Jones Lang LaSalle, a global commercial real estate firm, including research, assisting with sales transactions, and generating office leasing opportunities.

"I am thrilled and honored to be working with such a well respected company," said Olson. "In my previous role I had the privilege of working with the Grossmans on behalf of two of their office properties and was able to see firsthand what a smart, hardworking, and capable group of real estate professionals they are."
