Amauri G. Costa is a dual-qualified (Brazil/District of Columbia) attorney focused on cross-border corporate and commercial transactions, ranging from complex mergers, acquisitions and joint ventures to structured finance and trade finance matters. His transactional practice focuses on representing US- and Europe-based companies doing business in Latin America, and foreign companies doing business in the United States.

For nearly a decade, Mr. Costa represented a key U.S. agency in project finance transactions for small-and-medium sized enterprises in Latin America, Eastern Europe, and Asia.

Mr. Costa earned his LL.M. from Queen Mary and Westfield College in London in 1995, his graduate specialization in Brazilian corporate and commercial law from University Mackenzie in Brazil in 1991 and his law degree from the Law School of the University of São Paulo in 1990.
