Willis Re has appointed Jonathan Ogilvie (pictured, left) as global head of non-marine specialties and Chris Dart (pictured, right) as head of treaty reinsurance, Bermuda. Both join from Guy Carpenter and take up their roles immediately.
Ogilvie brings more than 20 years of experience across insurance, reinsurance, and retrocession in London and Bermuda. At Guy Carpenter, he served as head of property retrocession in Bermuda and held management positions in London across property, specialty, and casualty lines.
Dart joins with 23 years of experience in property treaty and retrocession reinsurance. He was most recently managing director and head of property treaty Bermuda at Guy Carpenter. Before that, he was a senior broker at John B. Collins & Associates in Bermuda.
The two appointments are part of a broader wave of hires Willis Re confirmed on June 11. On the same day, Willis Re named John Fletcher as CEO of Willis Re Bermuda and Jim Summers as CEO of global specialties. Fletcher previously served as CEO of Guy Carpenter Bermuda, a role he held since 2018.
The four appointments mark a significant consolidation of leadership across Willis Re’s London and Bermuda units.
The day’s hires form part of a recruitment drive that has brought roughly 80 professionals from Guy Carpenter to Willis Re since mid-2025. The campaign has covered property retrocession, specialty lines, analytics and life reinsurance.
Willis Re has been building out its platform across London, Bermuda, and Asia at the same time.
Lucy Clarke, board member of Willis Re, said the appointments strengthened the firm’s capabilities and market reach.
“Their appointments represent an important step in our continued development, enhancing our capabilities, broadening our market reach and positioning us to support clients globally with increasingly sophisticated solutions,” she said.
The scale of that campaign prompted Guy Carpenter to take legal action. A High Court judgment in February 2026 found that Fletcher and Summers improperly assisted Willis Re’s hiring push before leaving Guy Carpenter in mid-2025.
The court identified unlawful means conspiracies involving the sharing of confidential compensation data. It rejected the broader allegation of a systematic poaching scheme.
Ogilvie said Willis Re’s combination of specialist expertise and analytics capabilities created a strong client proposition.
“The combination of specialist sector expertise and advanced capabilities across data, technology and analytics creates a strong proposition for clients across the non-marine specialty market,” he said.
Dart said treaty reinsurance clients needed advice that went beyond technical knowledge.
“As treaty reinsurance programmes become more complex, clients increasingly require advice that combines technical excellence, market insight and creativity,” he said.
