Insurance Broker Marsh & McLennan Names New CEO

Insurance broker and benefits firm Marsh & McLennan said Chief Executive Officer Daniel S. Glaser will retire at the end of the year and Chief Operating Officer John Q. Doyle will succeed him.

Mr. Doyle’s promotion to the top job mimics Mr. Glaser’s own path back in September 2012. Then, Mr. Glaser, the chief operating officer, was named CEO. Mr. Doyle, who is 58, will take over from Mr. Glaser, now 62.
