Transactional powerhouse Alta leverages its full-service model and the support of offices in Costa Rica, El Salvador and Honduras to advise on big-ticket domestic and cross-border M&A deals, along with the full spread of related tax, labour and environmental issues. Acting for an array of local, regional and international companies and financial institutions, the team is also well equipped to advise on corporate structuring, joint ventures, and compliance and corporate governance matters. Managing partner Marcos Ibargüen, who is noted for his expertise in Guatemala’s newly enacted competition law, and pro bono practice head María Isabel Luján lead the six-partner team, which also includes Andrés Lowenthal, a go-to adviser to companies and investment funds in the US and Latin America; compliance practice head José Quiñones; Alejandro Cofiño, who contributes additional energy and finance expertise; and Melissa Echeverría, who is skilled in M&A and private wealth matters. Of counsel Santiago Granados, a contact for cross-border transactions, and senior associate Ignacio Grazioso provide key support. Since publication, Grazioso has been raised to the partnership - effective as of March 2026 - and Granados has left the firm for an in-house role.
