NETHERLANDS – Reinoud van den Broek, chief executive at Aon Hewitt Netherlands, and Jan Willem Siekman, executive director for retirement and financial management at Aon Hewitt, have indicated that they will leave the company, after four and three years, respectively.

During the coming months, they will transfer their tasks and contacts to the new management team, consisting of Pascal Hogenboom, Frank Driessen and Judith van de Ree, the company said.

Hogenboom will become responsible for operational aspects, broking and financial results.

In addition, he will be the team's link with the Dutch benefits administration business.

Driessen will be tasked with client activities, client retention and sales, whereas Van de Ree is to focus on staff development and improvement of quality and efficiency of client services.

According to Aon Hewitt, Van den Broek and Siekman will continue supporting the new management through knowledge transfer, as well as through client and contact introductions until the end of December.

After that, they will be "looking for a new challenge", it said.

Van den Broek and Siekman have not disclosed their plans for the future.
