CHICAGO, 2 May 2025 - Aon plc (NYSE: AON), a leading global professional services firm, today named Anthony DiLorenzo as head of US casualty for Reinsurance Solutions, effective immediately. 

In his new role DiLorenzo will be responsible for leading casualty broking teams to deliver insights and solutions to clients, combining transactional expertise with data and analytics excellence.

Casualty reinsurance is an increasingly important area of focus for Aon’s insurer clients as they manage the increasing severity of existing and emerging long tail risks, and respond to the evolving technological and regulatory environment. 

DiLorenzo assumes the role from Amanda Lyons, who was appointed Aon’s global product leader for Reinsurance Solutions in May 2024 to accelerate Aon’s product segment strategy across property, casualty, agriculture, credit, and cyber. 

Nick Nudo will assume DiLorenzo’s former role as head of US excess and umbrella.

Steve Hofmann, US CEO for Reinsurance Solutions said: “We are proud to celebrate and elevate Anthony, who, in his 13 years at the firm, has demonstrated exceptional leadership and expertise. As the former leader of our excess liability segment, he successfully oversaw large casualty relationships and delivered exceptional value to clients.”
