Danielle Giffuni


Danielle represents individual, corporate, and institutional clients facing complex, high-stakes criminal and regulatory investigations initiated by the full slate of federal and state financial services regulators. Her understanding of law enforcement priorities and experience with agency officials enable her to develop sophisticated defense strategies and guide clients through the complex demands of regulatory investigations and criminal prosecutions.

Danielle has advised clients in investigations launched by the Department of Justice (DOJ), Securities and Exchange Commission (SEC), Commodity Futures Trading Commission (CFTC), Office of Foreign Assets Control (OFAC), New York Department of Financial Services (NYDFS), Financial Industry Regulatory Authority (FINRA), and the offices of state attorneys general. She has also advised clients in numerous parallel actions conducted by federal and state officials.

Danielle has helped numerous clients avoid criminal charges and minimize penalties by conducting internal investigations, preparing voluntary self-disclosures, and cooperating with agency investigators and officials. In today’s era of rapid technological change and an increasingly mobile, connected workforce, she also helps clients understand recordkeeping and data-preservation obligations, issues surrounding the use of personal devices for business communications, and other emerging issues.

Among other matters, Danielle has defended allegations of market manipulation, securities fraud, insider trading, and obstruction of justice, as well as violations of U.S. economic sanctions, anti-money laundering laws and regulations, the Foreign Corrupt Practices Act (FCPA), the Bank Secrecy Act (BSA), and related anti-corruption and anti-bribery statutes.

Danielle also represents banks, private investment funds, broker-dealers and hedge funds—as well as their executives and traders—in investigations and enforcement proceedings arising under the federal securities and commodities laws.

In addition to her work on behalf of firm clients, Danielle is dedicated to helping ensure equal access to the law by providing pro bono counsel to indigent clients facing criminal prosecution. For her service, she received Crowell’s George Bailey Pro Bono Award in 2022.

Prior to joining Crowell, Danielle was a senior associate in the Financial Crimes Unit at PricewaterhouseCoopers. She also served as an assistant district attorney in the Frauds Bureau at the Kings County District Attorney’s Office in Brooklyn. Prior to law school, Danielle served as a paralegal specialist in the U.S. Attorney’s Office for the Southern District of New York from 2005 to 2007, as part of the office’s Securities and Commodities Fraud Task Force.
