Liberty Mutual to Expand Boston Headquarters

Insurer Liberty Mutual Group says it will spend $300 million to expand its global headquarters in Boston, a move that’s expected to add 600 new full-time jobs for the insurer.

The insurer already has more than 2,500 employees in its Boston headquarters, making it one of the largest private employers in the city.

Liberty Mutual recently acquired the former Salvation Army building and the Benjamin Franklin Smith building, which are located adjacent to the current Liberty Mutual home office campus at 175 Berkeley St.

Edmund F. Kelly, Liberty Mutual Group chairman, president and chief executive officer said, “We thank Mayor (Thomas) Menino, Governor (Deval) Patrick and their staffs for working so hard and creatively with Liberty Mutual to make this investment in Boston and its future economically attractive.”
