Two international arbitration partners in New York have joined K&L Gates from Cozen O’Connor, opting for a larger, global platform and allowing K&L to fill a gap in its international arbitration practice.

Martin F. Gusy and Matthew J. Weldon joined K&L Gates in New York, the firm announced Monday. Gusy had chaired the international arbitration group at Cozen O’Connor. He and Weldon have been practicing together for six years, three at Cozen O’Connor and three before that at a boutique firm Gusy founded.
