Insurance and reinsurance broking group Marsh has expanded Lisa Quest’s responsibilities to include the role of UK chief executive (CEO), effective April 6, 2026. She succeeds Chris Lay, who is retiring from the company.
Quest, currently head of UK and Ireland at Oliver Wyman, will work with Marsh UK business leaders to develop the company’s commercial strategy.
Headquartered in London and reporting to Flavio Piccolomini, CEO of Marsh International, Quest will also work to strengthen and expand client relationships across Marsh’s four businesses and drive innovative, data-driven solutions to support organizations in the UK’s diverse economy.
Quest joined Oliver Wyman in 2006 after previously working as a private equity investor, returning in 2013 as co-head of the European Government and Public Institutions practice.
In 2023, she was appointed head of UK and Ireland. Quest has global experience and deep expertise in data and analytics, future workforce and organizational design.
In addition, Quest works extensively with the UK government on key national priorities, including pay equity, defense financing, flood risk and resilience, and supports the establishment of new government agencies, including the National Wealth Fund.
Piccolomini commented: “With her global leadership experience and management consulting expertise honed across many of the world’s leading businesses, Lisa is perfectly positioned to guide our growth as we create and deliver exceptional services to support our UK clients and enable them to continue to thrive. Her appointment is testament to the deep talent base we have across the firm.”
Quest added: “The UK is renowned for its creativity, innovation and entrepreneurial spirit, but many organizations of all sizes are dealing with an increasingly volatile risk landscape. I look forward to working with our colleagues and clients to turn these risks into opportunities and support their future growth.”
