[ Who We Are ]

León Barrena Rodríguez & Partners LLP is a multidisciplinary professional services firm advising a diverse portfolio of clients across North America.

We specialize in complex legal, accounting, and government affairs matters, as well as complementary practices that demand strategic, cross-disciplinary insight and flawless execution.

LBR operates as a strategic risk integrator: preserving client access, cross-border connectivity, institutional credibility, legal certainty, and decision-making optionality across the U.S.–Mexico security and trade corridor. Through the coordinated deployment of strategic litigation and counseling, integrated government affairs, and top-tier real-time analytics, LBR builds the most effective institutional bridge between the United States and Mexico. This integrated model allows clients to navigate regulatory friction, political volatility, and security asymmetries with precision, maintaining continuity and leverage where others encounter constraint or withdrawal.

Our firm blends the rigor and sophistication of an international legal practice with the agility and personal focus of a boutique advisory team. We partner with corporations, investors, and institutions to navigate high-stakes transactions, disputes, and regulatory challenges with precision, clarity, and confidence.
