Bon-Ton Stores has announced that Bud Bergren will become chairman of the clothing retailer following Tim Grumbacher's resignation.

Grumbacher will remain a director of the company and has been appointed as strategic initiatives officer.

Bergren has been president and CEO of the retailer since 2004, joining after the acquisition of the Elder-Beerman Stores, where he was president and CEO.

Last week, the company appointed Brendan Hoffman as president and CEO of the company. He will join the retailer from Lord & Taylor.
