Whether practicing civil or commercial litigation, arbitration or antitrust, Omar Guerrero is a lawyer that has paid the "10 thousand-hour rule."

Based in Mexico City, Omar co-heads the arbitration and litigation practice and co-heads the antitrust practice of our Mexico offices. Omar knows the importance of being a team player, providing bold solutions for clients, and the merits of being a fierce competitor.

Omar joined Hogan Lovells (formerly Barrera, Siqueiros y Torres Landa) in 1993, immediately after graduating top of his class and summa cum laude. He became partner in 2000. He holds three post-graduate degrees including an LL.M from LSE (with merits). Since joining the firm, he has advised companies in the pharmaceutical, hospitality, telecom, food, construction, IT, and agro-business industries to advance their business objectives whether in a dispute or antitrust matters.

Omar is a passionate litigator. His storytelling and advocacy has convinced domestic and international arbitral tribunals, judges throughout Mexico, and even justices at the Supreme Court to rule in his client's favor. He has also acted as arbitrator in domestic and international disputes where he sits – at the other side of the table – deciding cases in which he's entrusted. Omar has also developed a significant practice in administrative litigation, including discrimination cases.

Antitrust is Omar's other passion. He helps companies in mergers, cartel investigations, and other antitrust-related proceedings. He embraces a hands-on approach when tackling his cases. He advises, trains, teaches, and lives antitrust law. Omar tries cases before competition authorities and federal courts, including the Supreme Court.

Omar also enjoys academia. He has written more than 40 thought leadership pieces on competition, litigation, and arbitration, and he speaks on the topics regularly. These experiences instill in Omar a commitment to provide valuable solutions for clients.
