Continuing its hiring streak, Greenberg Traurig has brought in four litigation partners from Cadwalader, Wickersham & Taft, including Louis Solomon, who was co-chair of the litigation department.

Solomon, Hal Shaftel, Colin Underwood and Michael Lazaroff joined Greenberg Thursday as shareholders in New York. Solomon is now co-head of Greenberg’s international litigation practice. The attorneys joined Cadwalader six years ago from Proskauer Rose.
