Oliver Wyman’s Lisa Quest named new CEO of Marsh in UK market
Marsh – the parent of Oliver Wyman, Marsh Risk, Mercer and Guy Carpenter – has appointed Lisa Quest as the new CEO of its UK business. She succeeds Chris Lay, who is retiring from the business.
Lisa Quest currently serves as the Head of UK and Ireland at Oliver Wyman, a role she has held since early 2023. In this additional role, Quest will lead Marsh’s strategic direction and commercial strategy in the UK market. She will focus on strengthening and expanding Marsh’s four businesses as well as developing new offerings for its diverse base of clients.
“The UK is renowned for its creativity, innovation and entrepreneurialism, yet many organisations of all sizes are navigating an increasingly volatile risk landscape,” said Quest. “I look forward to working with our colleagues and clients as we turn these risks into opportunities and support their future growth.”
With annual revenue of over $24 billion and more than 90,000 colleagues, US-headquartered Marsh is one of the globe’s largest professional services firms. In October last year, the group launched a refreshed brand identity and organisational structure, under which Marsh assumed the group’s brand from Marsh McLennan.
Commenting on the appointment, Flavio Piccolomini, CEO of International at Marsh, said: “With her global leadership experience and management consultancy expertise, which has been honed with many of the world’s leading businesses, Lisa is well-placed to steer our growth as we create and deliver exceptional services that support our UK clients and enable them to continue to thrive. Her appointment is testament to the deep bench of talent we have across the firm.”
