After three years serving as U.S. ambassador to Czech Republic, litigation partner Andrew Schapiro has returned to Quinn Emanuel Urquhart & Sullivan, trading his old office in Prague for some new digs in Chicago and New York.

“It was an easy choice for me,” Schapiro said of his return to Quinn Emanuel, which he first joined in 2011 from Mayer Brown. “There’s a culture here that I think is remarkable because on the one hand you have a firm that presents itself to the outside world as incredibly tough and aggressive, yet internally is the most collegial place I’ve ever worked.”
