Global insurance and reinsurance brokerage and risk advisor Aon has appointed Helene Madell as chief executive officer (CEO) of its global brokerage centers, effective June 1, 2026, subject to regulatory approval.
In her new role, Marder will report to Christian Hofmann, global CEO of commercial risks. She will lead the London-based Global Brokerage Centre, Aon’s wholesale and specialist brokerage business.
Madell’s responsibilities include bringing together deep subject matter expertise and global capabilities to help clients address complex and interconnected risks.
Most recently, she served as Head of Property, Casualty and Crisis Management for Global Brokerage Centers, supporting brokers’ global networks across these lines of business and working closely with market teams to deliver solutions to clients across geographies.
Aon said Madell played a key role in strengthening connectivity between brokerage centers and providing market insights and placement strategies for global client needs. She joined Aon in 2018 as managing director and chief brokerage officer in Australia, before returning to the UK to serve as chief brokerage officer for Aon’s UK retail business.
Prior to this, Mader had an extensive career in the London insurance market, having held senior leadership roles at Willis. She chairs Aon’s UK Product Governance Committee and is a member of BIBA’s International Wholesale and Advisory Committee.
Commenting on the appointment, Hoffman said: “As we continue to advance Aon’s joint strategy and help clients navigate increasing volatility and complexity, Helene’s leadership, market insights and deep connections across industries will drive how we bring the best of Aon to clients around the world.
“Helene has a proven track record of building high-performing teams and delivering data-driven solutions to help clients make better decisions.”
Mader said: “It is a privilege to lead the Aon Global Brokerage Center at such an important time for our clients. The risks our clients face are complex and increasingly interconnected.
“Our role is to bring together Aon’s best strengths – global expertise, deep market relationships and global production capabilities – to ensure the right solutions are delivered to clients in a highly dynamic risk environment.”
Aon’s global brokerage centers provide insight-driven risk transfer advice, placement solutions, proactive market insights and claims expertise.
The firm works regionally and nationally to structure and manage complex placements for clients across multiple specialty areas, supported by broad claims advocacy capabilities.
