Outten & Golden, a leading plaintiffs-side employment law firm, has elevated longtime class action litigator Adam Klein to become its managing partner after years of stewardship from founding partner Wayne Outten.

The law firm announced the leadership transition in a statement Monday, saying Klein assumed his new role Jan. 1. Although Outten is leaving the managing partner position, he will move into a chairman role at the firm he co-founded in 1998 alongside now-retired partner Anne Golden. Outten will also continue practicing law as a co-leader of the firm’s executives and professionals and whistleblower retaliation practices, and he’ll continue to serve on the firm’s executive committee.
