Aon Hewitt Switzerland is set to lose one of two heads of investment consulting, IPE understands.

Willi Thurnherr, chief executive at Aon Hewitt Switzerland, confirmed Beat Zaugg’s departure to IPE.

When asked about a timescale for Zaugg’s departure, Thurnherr said it would be over the course of the summer.

Zaug is currently head of the investment consulting business for German-speaking clients in Switzerland, based in Zurich.  

He has been with Aon Hewitt for a number of years but initially worked at Watson Wyatt, which promoted him to partner in 2003.

At the firm, he was also head of investment consulting.

Thurnherr noted Zaugg would not be immediately replaced, as Dominique Grandchamp – who in February was appointed head of the department for French-speaking Switzerland, or Romandie – would be able to cover both.

“We are not actively looking for a replacement right now,” Thurnherr said.

Grandchamp previously worked at rival consultancy Mercer and is currently based in Geneva.

He has worked as a management consultant at PwC and a relationship manager at Harcourt Investment Consulting.

Prior to joining Mercer in 2011, he spent four years as CIO at Nara Capital, a fund of hedge funds manager.
