Buchner Succeeds Wehrenberg as Campbell Mithun Chief Exec

It took a couple of months, but Minneapolis-based IPG agency Campbell Mithun has finally found a new CEO in Rob Buchner, a nearly 25-year Fallon vet who actually kicked off his ad career at the former agency as an account executive in the mid-80s. Buchner replaces Steve Wehrenberg, who remains on as a consultant for CM but has taken a leadership position at the University of Minnesota’s Journalism/Mass Communications program. Buchner, meanwhile, had spent the last nine years at Fallon serving as its chief marketing officer. He will assume his CEO post at Campbell Mithun on July 8.
