Our Business

​Since 1912, we've grown our organization into the fifth largest global property and casualty insurer - based on 2018 gross written premium - by maintaining our commitment to the belief that progress happens when people feel secure. At Liberty Mutual Insurance we work hard every day to support our customers and our people, so they can protect their families, build their businesses and invest in their futures.

We are headquartered in Boston, but our people, our customers and our reach span the globe. So to better serve our global customers and employees, we are organized into three business units.
