Moynihan succeeds Studer as leader of Marsh Management Consulting and Oliver Wyman. He will join the executive committee and report to John Doyle, president and CEO of Marsh. He will remain based in London.
The changes complete a transition outlined in March, when Marsh said Studer would move to Marsh Risk, succeeding Martin South, who shifted to an enterprise-wide chief client officer role.
“Ted brings extensive leadership experience and a proven track record of driving transformation and growth in the consulting sector. His deep expertise advising clients on complex business opportunities and challenges makes him the ideal leader to guide the continued success of Marsh Management Consulting and Oliver Wyman and contribute to our vision of making Marsh the most impactful professional services firm in the world,” said Doyle.
Moynihan has spent three decades at Oliver Wyman, most recently serving as global head of industries and previously as global head of financial services. His work has focused on strategy, risk, and transformation.
“It is a privilege to lead Marsh Management Consulting and Oliver Wyman at such a pivotal moment and build on our legacy of delivering exceptional client value through deep industry knowledge and innovative thinking,” said Moynihan. “Together with our talented colleagues, we will continue to help clients navigate complexity, adapt and build resilience while investing in our people and capabilities.”
Studer joined Oliver Wyman in 1997 and held senior roles across its consumer, industrial, and financial services practices before becoming CEO in 2021.
“Ted is highly respected within Marsh and across the public and private sectors for his perspectives on the issues reshaping business, economies, and societies,” said Studer. “Through his leadership, the business will continue driving impact, helping clients of Marsh and Oliver Wyman to transform and grow.”
Studer said on his LinkedIn page that he has been with Oliver Wyman since graduation and considers its future deeply personal, adding that the firm is in excellent hands with Moynihan. “Ted is highly respected, with deep expertise spanning clients, industries, and society,” he said, noting that Moynihan’s leadership will ensure growth for clients across both Oliver Wyman and Marsh while supporting the development of teams.
He said the succession process identified a group of senior leaders who could be future candidates for the role and expressed confidence in how the team will work together. “In my seat at Marsh Risk, our partnership will be invaluable.”
The leadership updates follow last year’s announcement that Marsh McLennan would adopt the Marsh brand across its businesses beginning in 2026, with a transition period extending into 2027. The plan includes aligning capabilities across its risk, consulting, and advisory businesses under a unified structure.
That announcement also introduced a Business and Client Services unit, consolidating technology, data, and operations teams to support client delivery across business lines.
Within that structure, Oliver Wyman will continue operating under its name while positioned as part of Marsh’s consulting structure.
Recent activity at Oliver Wyman includes a partnership with Cultivating Leadership focused on leadership and culture advisory alongside strategy and execution.
The appointments place executives with consulting and advisory experience at the head of two units central to Marsh’s risk and consulting operations.
Marsh has said its direction involves combining advisory capabilities with data, analytics, and technology across its businesses. The changes complete a sequence of leadership moves tied to that structure, with both executives now part of the company’s executive committee.
