The seasoned executive has been interim manager and consultant at several companies since 2001, after holding important sales and marketing positions since 1982 at various companies including Henkel, Mars and Villeroy & Boch. Andersen, who has been a top manager at Ecco for many years, was appointed to run MBT at its head office in Switzerland in 2009, taking the place of an interim manager, Ken Pucker, who had replaced Richard Litzel. Andersen is returning to his native Denmark, citing family reasons. He will be running an up-and-coming Danish jewelry company there.
