Marsh Risk says Nick Studer will become CEO and president from next month.

Mr Studer, currently CEO of Marsh-operated consultancy Oliver Wyman, takes over from Martin South, who will become Marsh chief client officer.

The pair will report to Marsh CEO and president John Doyle and remain on the company’s executive committee.

Mr Doyle says the appointments “will help us accelerate growth, increase our agility, unlock additional value for our clients, and realise our vision.

“Nick joined Oliver Wyman nearly 30 years ago, and in the last five years, as its CEO, has driven tremendous growth. 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 its trajectory of growth and service excellence.

“[Mr South] has deep relationships across industries, and as chief client officer will bring our unique capabilities together to help clients navigate this highly complex macroenvironment.”
