Her bilingual and bicultural experience allows her to assist clients whose matters require sophisticated legal judgment across jurisdictions.

Estefania has represented individuals and whistleblowers in complex cross-border investigations involving the Foreign Corrupt Practices Act, Bank Secrecy Act, Commodity Exchange Act, fraud, anti-money laundering allegations, and related enforcement matters before the U.S. Department of Justice, the Securities and Exchange Commission, and other agencies.

Before practicing in the United States, Estefania was a Mexican anti-corruption litigator and co-founded TOJIL, a nonprofit organization dedicated to combating corruption and impunity. Through her work with TOJIL, she helped secure the first judgment recognizing a nongovernmental organization as a victim of corruption in a criminal prosecution, allowing the organization to participate as a party in criminal proceedings. The groundbreaking case reached the Inter-American Commission on Human Rights and helped advance innovative anti-corruption criminal litigation across Latin America.

Estefania previously served in senior positions at Mexico’s Attorney General’s Office, including as a Federal Prosecutor and Head of the Immediate Attention Unit of Internal Affairs. She has also served as an advisor to the Office of the Executive Secretary of Mexico’s National Security System and as a consultant for both the U.S. Embassy and the U.K. Embassy in Mexico.
