Kenneth VianaleKenneth Vianale is a trial attorney focusing on complex civil, securities, and white-collar litigation.

Mr. Vianale began his career as an associate with Shearman & Sterling in New York City. He later served as an Assistant United States Attorney for the Southern District of New York (1988-1995). During that time, he worked principally in the Securities Fraud Unit and ended his tenure with the government as Deputy Chief of the Criminal Division. In 1992, he prosecuted U.S. v. Ostrander, and obtained the conviction of a former portfolio manager of Fidelity Investments charged with accepting unlawful compensation from Michael Milken. In 1993, Mr. Vianale led the government’s criminal investigation into alleged fraud in the sale of Prudential Securities’ public offerings of oil and gas limited partnerships. The innovative deferred prosecution agreement reached in this case, with the requirement that the defendant corporation follow rigorous conditions and retain a monitor to ensure compliance, is recognized as among the first such agreements reached between a prosecuting office and a corporation.

Mr. Vianale actively litigates complex civil actions, at the trial and appellate level, including actions on behalf of shareholders of public companies and other investors. He also defends individuals, businesses, and corporations in civil lawsuits, including actions alleging claims for trade secret theft, violations of the federal Consumer Protection Credit Act, and asset recovery or “claw back” claims brought by the SEC. He has been named in the 2014 Florida Super Lawyers and the 21st Edition of The Best Lawyers in America.
