Global insurance broker and risk advisor Marsh has appointed Nick Studer as president and chief executive officer of Marsh Risk, succeeding Martin South, who will serve as Marsh chief client officer across the enterprise, effective April 1, 2026.
Studer and South will continue to serve on the company’s Executive Committee and report to Marsh President and CEO John Doyle.
Studer currently serves as CEO of Oliver Wyman and Marsh Management Consulting. He joined Oliver Wyman in 1997 and has nearly three decades of industry experience, holding senior consulting roles in its consumer, industrial and financial services practices.
He has also served on a number of cross-industry organizations, including as a founding director of TheCityUK and a founding advisory board member of the FICC Market Standards Committee.
South rejoined Marsh in 2007 as CEO of multiple regional businesses, including Asia Pacific, the UK and Ireland, Europe, the United States and Canada, before becoming president and CEO of Marsh Risk in 2022.
He originally joined the company in 1985 at Bowring Marsh. He has also held leadership roles at Zurich Financial Services, where he served as a member of the Group Management Committee, responsible for all Zurich operations outside North America and Europe, and as CEO of Zurich’s London operations.
Doyle commented: “Our vision is to make Marsh the most influential professional services firm in the world. These appointments will help us accelerate growth, increase agility, unlock additional value for clients and deliver on our vision.
“Nick joined Oliver Wyman nearly 30 years ago and, as CEO, drove the firm’s tremendous growth over the past five years. His experience advising corporate and public sector leaders on risk and transformation makes Nick the ideal executive to continue Marsh Risk’s market leadership and further drive its growth and service excellence.
“Martin has decades of experience serving customers and driving innovation. He has deep relationships across industries, and as chief customer officer, he will bring together our unique capabilities to help customers navigate this highly complex macro-environment. Martin will also work on applying artificial intelligence and other new technologies to enhance the customer experience. I look forward to their continued contribution to our customers and Marsh’s success.”
“I am honored to lead Marsh Risk and excited to continue our mission of evolving into a disruptive risk advisor, full-service risk intermediary and passionate advocate for our clients,” said Studer. “The business has always been home to some of the most talented and dedicated risk and insurance professionals in the world. With our team, powerful data and analytics, and AI-enhanced client experiences, we will continue to help clients protect what matters most: their people, assets and future.”
South added: “The touchstone of all of Marsh’s business is that we put our clients at the center of everything we do. With our strong and broad expertise and keen understanding of our clients’ needs, we are able to serve them like no other professional services firm.
“I’m excited for the opportunity to continue to grow our customer impact and help accelerate growth in this new role.”
