AnnaLou Tirol counsels clients on anti-money laundering (AML) and fintech regulatory, compliance, and enforcement issues, drawing on two decades of government experience, most recently as Deputy Director of the U.S. Department of the Treasury’s Financial Crimes Enforcement Network (FinCEN).

Few lawyers share AnnaLou’s deep familiarity with AML laws and regulations. As FinCEN’s Deputy Director, the bureau’s second highest official, AnnaLou oversaw FinCEN’s operations, programs, and policy, including legislative and regulatory matters, public-private partnerships with financial institutions and fintechs, and enforcement and compliance matters related to the Bank Secrecy Act (BSA). Following Congress’ January 2020 enactment of the Anti-Money Laundering Act of 2020, AnnaLou led FinCEN’s implementation of the most significant legislation to modernize the BSA since the USA PATRIOT Act, including the Corporate Transparency Act’s beneficial ownership requirements.
