Posse Herrera Ruiz

National powerhouse Posse Herrera Ruiz hosts a well-staffed Medellín office that ‘anticipates client needs and adequately meets them’. The firm fields ten full-time on-site lawyers, including two partners, and is equipped to handle a broad spectrum of regulatory, transactional and contentious matters, with dominant local offerings in infrastructure, corporate transactions, public law, dispute resolution, real estate, tax, and international trade and customs law. As national leader of the infrastructure and public law practice, Medellín-based Cristina Vásquez is highlighted for her ’knowledge of infrastructure projects’; she recently advised Concesión Tunel Aburra Oriente on the negotiation and signing of the bilateral modification agreement to commence works on the second stage of the Oriente Tunnel project. International trade specialist María Paula Sánchez — who was promoted to partner in March 2024 — is also based in the city, while tax and international trade head Juan Camilo De Bedout divides his time between Bogotá and Medellín. Carolina Posada, who co-leads the dispute resolution department, similarly splits her practice between the two cities. Medellín-based tax litigator Ana Isabel Mejia provides associate support. In January 2025, former fintech associate director Julián Aguirre left to join fintech Cobre.
