September 26, 2022

Marsh McLennan said today that John Q. Doyle will take over as president and CEO effective January 1, at which point current CEO Daniel S. Glaser will retire.

Doyle, 58, was promoted to group president and chief operating officer of Marsh McLennan at the start of 2022. Prior to his most recent roles, Doyle was president and CEO of Marsh, the company’s risk advisory and insurance solutions business, from 2017 to 2021.

John Doyle

Doyle has over 30 years of management experience in commercial insurance underwriting and brokerage. He began his career at AIG and held several executive positions at the insurer, including CEO of AIG Commercial Insurance, and president and CEO of AIG Property and Casualty in the US.

Glaser, 62, has held the role of president and CEO of Marsh McLennan since 2013. He served as group president and COO prior to CEO. Glaser rejoined Marsh McLennan in December 2007 as chairman and CEO of Marsh – the firm where he began his career in 1982.

“Dan has had an extraordinary impact on Marsh McLennan, shaping it into a modern, dynamic company,” said H. Edward Hanway, chairman of the company’s Board of Directors, in a statement. “He expanded the business into new client segments, increased revenues from $12 billion to over $20 billion and grew the company’s colleague base. He successfully completed the company’s $5.6 billion acquisition of JLT in 2019; launched Marsh McLennan Agency which, in just over a decade, has grown to $2.5 billion of annual revenue and closed 100 acquisitions; and brought the firm together under a shared purpose. We are grateful for his contributions to the enterprise over many years.”

Hanway added that Doyle has the full support of the board, and pointed out that Doyle led Marsh to “outstanding earnings and revenue growth,” and is “a terrific strategist” who “found new ways to harness the collective strength of Marsh McLennan to deliver even greater impact with our clients, colleagues and communities.”

“It’s been an honor to lead this great company,” said Glaser. “Very few 150-year-old firms are as relevant, resilient and successful as Marsh McLennan is today. I leave with the same thought I had the day I became CEO: the best is yet to come for Marsh McLennan.”

Glaser will also retire from the company’s Board of Directors. Doyle will join the board as a director starting Jan. 1.
