Larry H. Krantz is a former federal prosecutor with over thirty years of trial and appellate litigation experience. He litigates white-collar criminal, regulatory, securities and complex commercial matters.

He has been described in Forbes as “among the most eminent defense lawyers in New York’s criminal bar.” His powerful cross-examination of the government’s star witness at a trial arising out of the Madoff fraud was described in Forbes as “hitting it off the facade of the New York Stock exchange.” He prides himself on representing his clients with tenacity, creativity, compassion and integrity.

In criminal and regulatory matters, Mr. Krantz represents corporate executives and others drawn into investigations conducted by federal and state authorities including: the United States Attorney’s Offices, the District Attorney’s Offices, the Securities and Exchange Commission (SEC), FINRA and various other regulators. Over the past three decades, he has been involved in many of the highest profile white-collar criminal cases and investigations including: the Madoff fraud (six month trial), the subprime mortgage fraud, LIBOR manipulation, Collateralized Debt Obligation fraud, Insider Trading at various hedge funds, the Enron fraud, and other major accounting, bank and securities frauds.

In civil matters, he regularly represents public and private companies (including financial institutions and insurers), as well as individuals, in the prosecution and defense of complex business disputes including: breach of contract claims, fraud claims, business dissolution disputes, unfair competition actions, and professional malpractice claims.

He also represents individual investors, brokers and brokerage houses in FINRA arbitrations and proceedings concerning alleged broker misconduct.

Mr. Krantz has successfully tried over 25 criminal and civil cases in federal courts, state courts and in arbitration forums.  He has also argued over 20 appellate matters.
