Representative Matters

  • Prosecuted the major executives of a $40 billion-a-year company who were involved in the theft of more than $150 million from a public company. Initiation of the investigation, along with the subsequent management of all case work, including taking pleas, supervising the investigation and trying one of the cases in question, resulted in an accountant's permanent barring from practicing accounting, the recovery of hundreds of millions of dollars and the conviction of three individuals. 
  • Initiated and led the investigation of money laundering and fraud at the Bank of Credit and Commerce International, which involved senior officers and individuals from 70 countries worldwide. Through the investigation and prosecution of officers and individuals, the team recovered $1.6 billion, and directly recovered $650 million for victims of the fraud. The prosecution caused the bank to close. 
  • During a securities fraud case, initiated and supervised the investigation and prosecution of 17 individuals involved in the corruption of a stock brokerage firm. Commitment to prosecuting the appropriate individuals led to the conviction of all 17 in question and the supervision of several hundred subsequent prosecutions that arose out of the initial fraud case. 
  • Led the investigation and conducted the prosecution of individuals involved in bank fraud in Caracas, Venezuela. Used bank documents and knowledge of fraud and money laundering to demonstrate that the individuals in question were guilty of fraud.


  • Secured an arbitration award of more than $14 million for a New York stock exchange client, which was the third-largest award in stock exchange history. Understanding the situation – that the defense was planning to catch the complainant in a lie and use the lie to discredit the entirety of his story – allowed an analysis of the matter and its possible solutions, which in turn made it possible to obtain the unprecedented award.
  • Won an $8.02 million claim for a client in an American Arbitration Association proceeding, which was the full amount of the claim.
