Curtis, Mallet-Prevost, Colt & Mosle said that it plans to launch a new outpost in Geneva next month, joining the small number of international firms with offices in Switzerland.

The office, Curtis’ 18th globally, will be headed by Paris-based international tax partner Marco Blanco, who oversees the firm’s European offices in London, Frankfurt, Paris, Milan, Rome and Istanbul. Blanco will split his time between Paris and Geneva once the doors formally open on May 15, the firm said.
