The competition and merger control department at Serrano Martínez CMA frequently secures key roles in Colombia’s most significant antitrust investigations, while also ranking among the country’s largest filers of pre-merger notifications. The team also shines in unfair competition disputes, including class actions, and regulatory compliance work. High-profile practice head Felipe Serrano is a former Deputy Superintendent of Industry and Commerce; he is currently representing local Uber subsidiary Rasier Operations in an antitrust investigation initiated by the SIC against the ride-sharing platform. The group also draws on the experience of Andrés Jaramillo Sanz, who was promoted to partner in January 2026 and is particularly noted for competition and regulatory litigation; and energy and gas head José Plata Puyana, who is also a qualified economist. A deep pool of associates includes senior Juan Felipe Traber, who co-heads the merger review practice together with Serrano; senior Saella Moreno, who joined from Philippi Prietocarrizosa Ferrero DU & Uría in February 2026 and specialises in competition, data privacy and consumer protection law; and intermediate Ana Sofía Cabrales, who supported on a string of merger reviews, regulatory matters and contentious cases during 2025/26. In August 2025, intermediate associate Fery Cure left to undertake an internship at the World Bank. The practice was notably strengthened in May 2026 with the hire of former CMS Rodríguez-Azuero practice head Lorenzo Villegas, along with associate Ana Cortés.
