The practice is co-led by three partners with distinct but complimentary specialisms: Javier San Martín  (civil and commercial disputes), Luis Eduardo Toro (bankruptcy and competition) and David Cademartori (public and administrative law). All handle assistance with consumer matters, including class action lawsuits and other actions that are filed by SERNAC and/or individuals. Key support comes from disputes practice senior associates Isidora Fernández and Cristián Pérez.

The practice also enjoys a successful track record before CONAR, while on the consumer side, the team handles consumer claims for high-profile clients, including Google. Head of the firm's tech, media and privacy group, Rodrigo Lavados, and well-known head of the competition practice, Juan Cristóbal Gumucio, are the partners to note; key support is provided by senior associate Felipe Fernández.

The team was further strengthened with the June 2019 hire of Antonio Rubilar, formerly in-house at ENAP, as a senior associate; he will focus on regulatory litigation, competition and antitrust, public law and the energy and natural resources sector. The firm is also a member of the Global Advertising Lawyers Alliance.
