Specialty insurer Hiscox has appointed Mary Boyd as chief executive officer of its USA business unit. She joins the specialty insurer on June 24, replacing Kevin Kerridge, who is stepping down after almost 30 years in the business.

Boyd joins Hiscox from home and auto insurance provider Plymouth Rock Assurance, where she has been CEO of its independent agency business since 2018. She began her career in actuarial roles before moving into leadership positions at The Hartford Insurance Company, ACE, Explorer Insurance and Chubb.

Hiscox Group CEO Aki Hussain said that Boyd’s “wealth of experience building and leading insurance businesses in the USA, and her deep understanding of the U.S. customer market, will be instrumental in scaling our U.S. business as we seize the opportunity ahead.”

Hiscox said that outgoing CEO Kerridge will operate in an advisory capacity over the coming months before leaving to explore outside opportunities at the end of September.
