DLA Piper LLP (US)'s rapid growth of its US-based Latin America practice is bringing significant rewards. It now has prominent talent across multiple practices, including energy and infrastructure. Partners and associates in its New York, Washington DC, Los Angeles, San Diego, Houston and Miami offices, now frequently work alongside colleagues in Argentina, Chile, Colombia, Mexico, Peru and Puerto Rico, as well as in Brazil (through Campos Mello Advogados in cooperation with DLA Piper). Many in the Latin America team are natives of countries in the region, or are native Spanish or Portuguese speakers. Margarita Oliva Sainz de Aja is head of Latin America banking and finance, and is based in New York after spending many years as a partner in Argentina; she is an experienced project finance specialist with an established client base of multilateral agencies, ECAs, commercial financial institutions, sponsors and project companies. Miriam Figueroa splits her time between New York and Puerto Rico, and has extensive expertise in infrastructure, power purchase agreements and public-private partnership contracts; much of her practice centres on Puerto Rico. New York partner Marcello Hallake is a prominent name in energy M&A, especially in Brazil-related deals; while Diego Peña is a key partner in Santiago. Bruno Soares joined the firm from what is now A&O Shearman in February 2024 and has subsequently become managing partner of the new Sao Paulo office.
