Marsh McLennan announces John Doyle will succeed Glaser as president and CEO when he retires at year end

Marsh McLennan has announced that John Doyle, 58, has been named president and chief executive officer, effective 1 January 2023. Daniel Glaser, 62, will retire from Marsh McLennan at year end following a decade leading the company.

Doyle has served as group president and chief operating officer of Marsh McLennan since January 2022, and prior to that was president and CEO of Marsh, the Company’s risk advisory and insurance solutions business, from 2017 to 2021.

Glaser has served as president and chief executive officer since 2013. Prior to 2013, he served as group president and chief operating officer of the Company. 

Glaser rejoined Marsh McLennan in December 2007 as chairman and chief executive of Marsh, returning to 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.

“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.”

Upon his retirement, Glaser will also retire from the company’s Board of Directors. Doyle will join the Board as a director effective 1 January 2023.

Doyle is an insurance industry veteran with more than 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 chief executive officer of AIG Commercial Insurance, and president and CEO of AIG Property and Casualty in the US.
