Global professional services company Aon has appointed Andy Marcell as its new CEO of Global Solutions.  

In this role, Marcell will oversee Aon’s integrated Risk Capital and Human Capital capabilities, encompassing the organization’s reinsurance, commercial risk, health, wealth and talent teams. 

Marcell, who joined Aon in 2015, will continue to serve as CEO of Reinsurance until John Neal assumes the position on 1 September 2025. 

Aon named Neal as the global chairman of Climate Solutions and global CEO of its Reinsurance arm in January this year.  

Marcell will report to Aon president and CEO Greg Case and remain a member of the Aon Executive Committee, the company said. 

Case said: “Building integrated capabilities to help our clients address risk and people issues is one of the core commitments of our 3×3 Plan to go further, faster in serving urgent client need.  

“Andy has made a tremendous impact integrating our solutions and enhancing the alignment of our Risk Capital and Human Capital capabilities and will advance our strategy to serve clients as one Aon United firm.” 

Marcell’s promotion follows his tenure as CEO of Risk Capital, where he unified the company’s commercial risk and Reinsurance solutions.  

He will present the company’s strategy for addressing client needs across both Risk Capital and Human Capital at its Investor Day on 9 June 2025. 

Last month, Aon named Lambros Lambrou, CEO of Human Capital, as its new global chief strategy officer.  

Marcell stated: “Lambros and the Human Capital leadership team have made tremendous progress integrating our Health, Wealth and Talent teams to deliver differentiated data, insights and expertise.  

“I am looking forward to bringing our Risk Capital and Human Capital teams closer together to address the unprecedented volatility and complexity facing our clients.”
