About Arnold Y. Castillo

Over the past 25 years working throughout Latin America and the Caribbean, Mr. Castillo has led and been involved in some of the region’s most high-stakes and complex corporate investigations into Foreign Corrupt Practices Act (FCPA), Bank Secrecy Act (BSA)/Anti-Money-Laundering (AML), asset tracing, construction internal fraud, environmental damage, money laundering, social conflict monitoring, and corruption in both government and corporate settings—often sparked by anonymous whistleblower reports. His extensive experience has allowed him to cultivate a wide-reaching source network of contacts across every country in the region, having worked in all of them and handled hostile situations for clients who had been defrauded by local partners. ​As a recognized reputation management and crisis advisor, Mr. Castillo has provided independent, third-party assessments for clients facing public allegations, media exposure, or regulatory interest. He is often called upon to evaluate reputational damage, mitigate regulatory risk, and support high-stakes negotiations with U.S. authorities, compliance officers, and prospective partners. ​His fact-finding background includes investigating internal fraud and corruption rings for multinational mining, energy, banks, and credit card corporations with multijurisdictional operations in the Andean region, Central America and the Caribbean where he deployed teams for intelligence-gathering assignments, IT digital evidence collection, and forensic accounting. Mr. Castillo has led hundreds of pre-transaction business intelligence, political risk, and due diligence investigations for foreign investors and international candidates applying for financial licenses worldwide. Mr. Castillo has led several investigation and litigation support teams on multiple occasions and presented testimony in arbitration proceedings in defense of his clients. ​Mr. Castillo has received the recognition of Global Leader in Investigations & Digital Forensics by Lexology Index (former Who’s Who Legal) from 2019 to 2025. The publication praises his sharp expertise, long-standing network, and professionalism in handling complex security and sensitive investigations matters.
