LONDON, Feb. 4, 2026 - Aon plc (NYSE: AON), a leading global professional services firm, today announced senior leadership appointments within its Reinsurance Solutions business in Greece and Cyprus. Effective February 16, 2026, Dimitris Lymperis will become chief executive officer for the region, while Evros Kyriakides will assume the role of managing director.
The new senior leadership team in Greece and Cyprus will focus on driving better decisions for Aon’s insurer clients in the region, helping them navigate volatility and emerging risks, and capture new profitable growth opportunities.
By expanding Aon’s range of treaty and facultative reinsurance solutions, advancing innovation in products and analytics and working closely with colleagues across EMEA, the leadership team will continue to deliver optimum value and data-driven insights to regional clients.

Lymperis added: “I am excited to take on this new role in which I aim to build upon the incredible foundations that Manolis put in place during his successful tenure, which allowed us to further enhance our delivery of client value in the region and drive better business decisions.”
