Throughout his professional career, prior to joining Gritwood, José Manuel was part of one of Mexico’s most prestigious law firms, where he participated in ICSID arbitrations against the Mexican State arising from investment disputes in the mining sector, as well as in commercial arbitrations before institutions such as the ICC and the ICDR. He has likewise participated in various administrative litigation proceedings through the filing of administrative review appeals, annulment actions, and amparo proceedings, as well as in the legal analyses of Preliminary Administrative Liability Reports (Informes de Presunta Responsabilidad Administrativa) issued by the Auditoría Superior de la Federación (Superior Audit Office – Mexico’s Supreme Audit Institution).

He also has experience in antitrust law, having participated in the proceedings to respond to preliminary opinions and merger notifications, as well as in financial law through securities issuance authorization processes before the Comisión Nacional Bancaria y de Valores (CNBV – National Banking and Securities Commission).

His dual background in law and international relations, combined with early exposure to high-complexity disputes before domestic and international forums, gives him a strategic and multidisciplinary perspective that enriches both legal analysis and the development of arguments in contexts where public and private law, international trade, and economic regulation converge.
