Arlo Devlin-Brown

Arlo Devlin-Brown is a co-founder and Managing Principal of Treanor Devlin Brown PLLC, where he represents companies and individuals in high-stakes government investigations, enforcement actions, and complex white-collar litigation. His practice centers on money laundering, sanctions, securities fraud, insider trading, corruption, and accounting fraud matters, and increasingly on the government's evolving approach to digital assets and cryptocurrency.

Before entering private practice, Arlo served as a federal prosecutor in the U.S. Attorney's Office for the Southern District of New York, where he was Public Corruption Chief and a leading securities fraud prosecutor. He led the prosecution of what was then considered the most powerful hedge fund in the world, securing $1.8 billion and a conviction in what remains the largest insider trading scheme ever charged, and brought groundbreaking anti-money-laundering charges against the largest U.S. financial institution, recovering a record $1.7 billion for victims of the Madoff Ponzi scheme. Together with firm co-founder Tim Treanor, he also spearheaded the DOJ's enforcement campaign against illegal internet gambling, which produced more than $3 billion in penalties and reshaped the industry. His work earned him the Department of Justice's Director's Award for Superior Performance and the John Marshall Award.

In private practice, Arlo has become a go-to adviser for companies and individuals confronting existential legal risk, particularly in the crypto and digital asset space. He has represented fifteen current and former employees of FTX and Alameda in criminal and regulatory investigations, a crypto lending platform building its subpoena-compliance and law-enforcement-interaction program, and a leading Chinese bank facing DOJ, OFAC, and NYDFS inquiries into sanctions violations, alongside several Fortune 100 companies defending insider trading investigations. A trial lawyer with more than fifteen federal jury trials to his name, he brings courtroom credibility that carries through negotiations as well as litigation, and is a frequent legal analyst for CNN, Fox, MSNBC, and the BBC.
