Marsh McLennan has announced that John Doyle (pictured) will be its new president and chief executive officer, effective January 1, 2023. He succeeds Daniel Glaser, who will retire at the end of the year after nearly a decade of helming the global professional services firm.

Doyle has served as group president and COO of Marsh McLennan since January 2022. Prior to that, he was president and CEO of Marsh, the company’s risk advisory and insurance solutions business from 2017 to 2021.

An insurance industry veteran with more than 30 years of management experience in commercial insurance underwriting and brokerage, Doyle 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.

“John has led Marsh to outstanding earnings and revenue growth and, as group president and COO, has found new ways to harness the collective strength of Marsh McLennan to deliver even greater impact with our clients, colleagues, and communities,” remarked H. Edward Hanway, chairman of the Marsh McLennan board of directors. “He is a terrific strategist and an exceptional leader who builds effective, diverse, and inclusive teams. With his leadership, the company is well positioned for continued growth.”

Hanway also praised the outgoing CEO, who had led Marsh McLennan through a period of significant growth and change. “Dan has had an extraordinary impact on Marsh McLennan, shaping it into a modern, dynamic company. He expanded the business into new client segments, increased revenues from $12 billion to over $20 billion and grew the company’s colleague base,” Hanway added. “We are grateful for his contributions to the enterprise over many years.”

Glaser lauded the Doyle’s appointment and said the incoming CEO had been “an indispensable partner” in delivering on Marsh McLennan’s strategy.

“John knows our businesses well and is focused on creating best-in-class solutions for our clients. I am confident that this organisation’s extraordinary success will continue under John’s leadership,” said Glaser, will also retire from the company’s board of directors.

In a statement, Doyle thanked his predecessor and the board of directors for their support and confidence.

“We have terrific momentum and the capabilities and expertise needed to drive innovation and growth, deliver critical client solutions, and create value for shareholders. I look forward to partnering with our 83,000 colleagues to write our next chapter,” Doyle said.
