John G. Moon

A former SEC branch chief and enforcement attorney, and a former federal prosecutor of financial crimes for the U.S. Department of Justice, litigator John Moon brings unrivaled skill and perspective in representing clients in securities regulatory matters, complex civil litigation, and white-collar criminal defense cases.

John represents financial institutions, public companies, and executives in wide-ranging and game-changing commercial litigation, internal investigations, and in civil and criminal investigations and proceedings brought by grand juries, the SEC, DOJ, CFTC, FINRA and state governmental entities. John has successfully represented institutions and individuals caught up in some of the largest financial fiascos of this century: FTX, Enron, S.A.C. Capital and Madoff. His civil litigation experience also includes a focus on structured finance, securitizations, and proposed multibillion-dollar “private label” RMBS settlements. Further, he has represented financial institutions in civil disputes involving CDOs, CLOs and capital markets.

A recognized authority in his field, John is often quoted by leading national publications and news outlets such as PBS Frontline, Vanity Fair, The New York Times, Law360, USA Today, The Philadelphia Inquirer, and The Washington Post, which have covered many of his high-profile wins over the years.

Before joining Olshan, in addition to his roles at the SEC and as a DOJ prosecutor, John was a partner in the Financial and Securities Industries Practice at a New York-based law firm. He also served as an executive director of litigation for the Americas at UBS Investment Bank in New York and as a Principal Consultant in the Banking, Finance and International Group of PricewaterhouseCoopers LLP.

During his tenure at the DOJ, John received a special achievement award from the U.S. Attorney General. Most recently, John was appointed Receiver by the Delaware Court of Chancery to run a high-tech public company.
