As Deputy Chief, Tim supervised the work of approximately 15 senior federal prosecutors conducting grand jury investigations and prosecutions of both violent crimes and sophisticated white-collar crimes, including money laundering offenses involving major financial institutions, fraud offenses in the pharmaceutical and insurance industries, and offenses involving fraud in the market for subprime mortgages. For several years, Tim was a member of the Organized Crime and Terrorism Unit, and in that capacity participated in the DOJ’s response to the terrorist attacks of September 11, 2001.

He also served as a clinical prosecutor in the U.S. Attorney’s Office for the Eastern District of New York.

He tried a dozen criminal cases, convicting all 24 defendants, and led the government teams in three major multi-month, multi-defendant trials. In addition, Tim briefed and argued numerous cases before the Court of Appeals for the Second Circuit. 

Earlier in his career, Tim spent several years in private practice as an antitrust litigator defending corporate clients against enforcement actions by the DOJ and the Federal Trade Commission. He was also a founding partner of Law Preview LLC, an educational services company.
