Winston & Strawn LLP

Winston & Strawn LLP has a large team of government investigations, enforcement and compliance specialists within its ranks, and – coupled with the firm’s strong focus on Latin America – it has a sizeable practice in the region. Much of this centres on Mexico, the Central American isthmus and Argentina. The firm represents a mixture of local companies along with foreign investors, and is noted for its links to state-owned enterprises in the region. In Mexico, the firm has experienced an uptick in engagements linked to cartels being designated as terrorist organisations. It is also active in sanctions-related matters thanks to the presence of Washington DC’s Cari Stinebower and others within its ranks. Recognised as a real Latin America specialist, Julissa Reynoso returned to the firm in 2024, having served as United States Ambassador to Spain and Andorra, and in senior positions in the White House; she has strong connections to state-owned enterprises in Mexico. Marcelo Blackburn also has extensive experience in government and internal investigations in Latin America, while Seth Farber is another key figure in white-collar criminal defence and internal investigations. Named individuals are based in New York unless stated otherwise.
