About McConnell Valdés LLC

McConnell Valdés, recognized as Puerto Rico’s powerhouse law firm, was established 1946 as a firm dedicated to representing financial institutions and manufacturing companies when Puerto Rico was embarked on an industrialization process that would bring to the island the giants of manufacturing and financial institutions.We have played a leading role in the creation and implementation of projects and important legislation in Puerto Rico. Throughout our history, we have worked on the most significant laws directed at economic development in Puerto Rico, including the Tourism Development laws of 1993, 2010 and 2016, the Industrial Incentives laws of 1998 and 2008, and the 2010 Renewable Energy Law. We have also been part of the development and construction of large emblematic projects in Puerto Rico, such as the Teodoro Moscoso Bridge, the José Miguel Agrelot Coliseum, Palmas del Mar and the Ritz Carlton Reserve Dorado Beach, among many others.We continue to maintain our leadership by creating niche practice areas such as federal financing, infrastructure & PPPs, tax litigation and international banking and financial entities. We also have the largest and one of the most influential government affairs practice teams in the island, as well as the largest litigation practice group in Puerto Rico.All our attorneys are bilingual (Spanish and English), and many are licensed and practice in federal and state courts, both in Puerto Rico and in various mainland jurisdictions. Our lawyers have received their law degrees from some of the world’s most respected law schools, including Boston University, Columbia, Georgetown, Harvard, New York University, University of Puerto Rico and Yale.
