Latinvex has ranked Haynes Boone Mexico City Office Managing Partner Patricia Mastropierro in its annual list of the top 100 female lawyers specializing in Latin America among international law firms for the ninth time. She is ranked in 2025 in the corporate M&A and aviation categories.
Mastropierro represents one of the largest U.S. airlines and its regional affiliates in more than 45 jurisdictions worldwide, and she has worked for more than 29 years on the airline’s international projects, including in the areas of commercial transactions and regulatory, aviation and litigation matters.
“Patricia’s consistent recognition by Latinvex is a testament to her exceptional legal acumen and leadership in cross-border transactions,” said Haynes Boone Partner Alberto de la Pena. “Her deep experience in both corporate M&A and aviation law continues to make a meaningful impact for our clients across Latin America and beyond.”
Latinvex’s criteria for selection included recent track record on major deals and business, prominence of the firm in Latin America and other factors. Research was based on data provided to Latinvex by the firms, publicly available data from the firms, M&A data from Refinitiv as well as third-party recognitions from Chambers, Legal 500 and others.
