Raised in New York City, educated at the most elite universities in the country, and tested as an Assistant United States Attorney for the Southern District of New York, Ryan Poscablo combines the knowledge, training, and experience of a skilled litigator with the savvy, street smarts, and instincts of a seasoned trial lawyer. Whether in the courtroom, the boardroom, or the conference room of a government agency, Ryan’s reasoned judgment and exhaustive preparation allows him to craft the right solutions for his client’s diverse legal issues.

The real secret to Ryan’s success as a public servant and as a corporate litigator is that he’s empathetic, perceptive, and extraordinarily good at reading people and gaining their respect and trust. And that matters, because no matter how technically complex or challenging a legal case may be, it always comes down to the character and qualities of the people involved.

An able and persuasive advocate, Ryan knows when to hold forth and when to hold back. And, although he’s a man of deep compassion and optimistic outlook, he’s not easily intimidated. His results speak for themselves: during the six years he served as Assistant United States Attorney, he was undefeated in every one of the 12 significant criminal trials where he served as lead counsel or co-lead counsel.

As a federal prosecutor, he conducted numerous investigations that charged bank, wire, mortgage and tax fraud, as well as identity theft, medicare and healthcare fraud, and money laundering. In addition, he led multi-defendant investigations that led to convictions for racketeering, terrorism, and violent crime.

Prior to his career in the U.S. Attorney’s Office, Ryan practiced at a large international law firm, where he served clients engaged in complex commercial litigation. He also represented clients in white collar antitrust matters before the U.S. Department of Justice, the European Union, and various regulatory agencies worldwide, as well as in follow-on multidistrict class action litigation.

Since returning to private practice, he has represented companies and individuals before the U.S. Department of Justice, various state attorneys general, the Securities and Exchange Commission, and the Commodity Futures Trading Commission, in cases involving securities fraud, criminal antitrust, corporate embezzlement and theft, medicare fraud and anti-kickback, bid-rigging, and public corruption. He has defended Fortune 500 companies in national class action litigations and serves as outside general counsel to leading healthcare and start-up technology companies, including blockchain and cryptocurrency companies.

Ryan also helps lead the Firm's higher education practice by representing colleges and universities in Title IX litigation and, using trauma-informed investigative techniques, serving as an external investigator for educational institutions in various internal investigations.
