Scott Zemser, who was hired by U.K. firm Allen & Overy less than two years ago in a major play to boost its finance team in the United States, has left to join Mayer Brown. He will be a partner and co-leader of Mayer Brown’s global lending group.

Zemser had joined Allen & Overy from White & Case in 2016 to become co-leader of the British firm’s leveraged finance practice. Two other finance partners, Alan Rockwell and Judah Frogel also made the move at the time. Those two remain at Allen & Overy.
