Under his leadership, the business has built strong client relationships, deep market expertise and an integrated team. Today, Aon is very well positioned to support clients in Germany with innovative solutions and global capabilities. We are grateful to Jan-Oliver for his outstanding leadership and contributions over the years.”

Thofern was born in Stuttgart in 1964 and earned an MBA in Management and Finance from the University of Wales, with a specialization in Banking. He began his career at Allianz Life Insurance Company, before joining Aon in 1993.

Until his retirement, Thofern will continue to perform his duties in full and his successor will be determined through the structured process already underway and announced in due course.
