LONDON, April 28, 2025 - Aon plc (NYSE: AON), a leading global professional services firm, today announced new appointments within Reinsurance Solutions’ Client Services function, which provides dedicated support to clients through expert claims handling and accounting, ensuring a seamless and responsive experience throughout the claims lifecycle.

Amidst increasing economic uncertainty, clients across the re/insurance industry increasingly prioritize claims and accounting services to help navigate complexity. Recent events such as the California wildfires and Hurricanes Helene and Milton, along with the war in Ukraine, have further emphasized the importance of a strong capital distribution chain.

To further strengthen Aon’s reinsurance global client advocacy services, the firm has appointed the following individuals:

• Steve Clark has been named global head of Claims and Client Services Advocacy for Reinsurance Solutions at Aon, where he will be responsible for Aon’s global advocacy proposition, ensuring that clients receive support and expertise in managing their claims. Clark will provide leadership and strategic vision to drive transformational change across geographies and solution lines, deliver business results and ensure Aon maintains its position at the forefront of the reinsurance industry. Clark will continue to report to Leonora Siccardi, global head of Client Solutions for Risk Capital and Reinsurance Solutions’ Chief Claims Officer at Aon.

• Ann Field has been named global head of Client Experience, where she will work closely with product and client segment leaders to improve advocacy, enhance client satisfaction, and drive business growth. Field will also work with Aon leaders across technology, Aon Business Services, and Client Advocacy to continue to improve delivery of the Client Services operating model. She will continue to report to Siccardi.

• Matt Moore has been appointed head of Client Services and Advocacy in North America for Reinsurance Solutions at Aon, reporting to Clark. Moore will be responsible for aligning North America Client Services, including claims, accounting and collateral functions, with Aon’s global advocacy model, and will offer strong collaboration with technology and strategy partners to identify and consistently execute North America transformational change.

• David Griffiths will expand his role as global head of Claims Strategy and Innovation to further enhance the firm’s claims proposition and assist with broader claims-related initiatives. 

Siccardi said: “Our clients face a highly complex environment when managing their claims and accounts. Aon recognizes the importance of continually evolving our services to meet our clients’ new challenges and demands in the current macroeconomic landscape. These new appointments will enable us to drive increased value and resilience for our clients.”
