As a highly decorated former federal prosecutor, Jason focuses his practice on representing corporations and individuals in white collar investigations involving the US Attorneys’ Offices, the Securities and Exchange Commission, the New York State Attorney General’s Office, and other agencies. He is a seasoned trial lawyer with extensive experience handling white collar fraud cases, internal investigations, crisis management situations, and regulatory enforcement matters.
Jason has the unique ability to represent a variety of clients, ranging from Fortune 100 companies to small businesses and high-profile individuals to nonprofit organizations. Jason’s work covers multiple industries including clients in finance, manufacturing, wholesale distribution, the defense industry, public relations, health care, and sports and entertainment, including high-profile celebrity clients. This year, Jason achieved a rare feat — convincing the Department of Justice not to bring charges against his client after the DOJ had a years-long investigation into the client’s alleged corrupt conduct, a stunning outcome that allowed our client to avoid criminal charges and further government enforcement actions. Jason also recently worked with a multinational firm who contracts with the government and had received a subpoena from the US Attorney’s Office relating to a bribery and kickbacks investigation. He conducted a thorough and complex internal investigation on behalf of the client to determine if there was any risk of legal or criminal liability. He is a frequent contributor to major publications including Law360, New York Law Journal, and the Albany Times Union, where he comments and authors pieces on cutting-edge legal issues and developments.
He also has substantial expertise in representing clients in the not-for-profit sector in various high-profile investigations and sensitive inquiries from state and federal agencies, including by the New York Attorney General’s Office and various New York State agencies. In addition, relying on his experience and perspective as a highly regarded former federal prosecutor in the Southern District of New York, he has also successfully made numerous criminal referrals to various governmental agencies, when appropriate and in the best interests of our clients. His credibility with law enforcement puts him in a unique position to be heard in these matters that are of the utmost importance to our clients.
Jason maintains a robust pro bono practice, providing legal assistance to asylum seekers, and political refugees among others. Most recently, he worked with a team of attorneys to secure Special Juvenile Immigrant Status (SJIS) on an expedited basis for a minor escaping gang-related violence in his home country, allowing the minor to seek lawful permanent residence in the United States.
From 2004 to 2015, Jason worked as a highly regarded federal prosecutor in the US Attorney’s Office for the Southern District of New York. During his tenure, he conducted 13 federal jury trials — including numerous high-profile cases — and never lost a trial. His most prominent trials included the prosecution of four men who plotted to blow up synagogues in Riverdale, New York, and a public corruption case involving a Yonkers City Councilwoman and her political patron, who were convicted of conspiracy, mail fraud, wire fraud, bribery, extortion, mortgage fraud, and tax fraud. Jason also handled many white collar fraud cases and successfully prosecuted three New York state senators as well as political aides and developers for corruption crimes and tax fraud. Jason led a team of prosecutors and numerous law enforcement agents who won the 2013 Office of the Director of National Intelligence’s Counterintelligence Award for Excellence.
After working as a federal prosecutor, Jason joined one of New York’s most prominent white collar litigation practices. When he left the government, Jason was profiled in The New York Times. He has briefed and successfully argued numerous cases on appeal before the US Court of Appeals for the Second Circuit. Early in his career, Jason worked at two international law firms and clerked for Judge Ricardo M. Urbina of the US District Court for the District of Columbia. He also worked for New York Governor Mario Cuomo for four years, serving for two years as his principal staffer — drafting remarks for the former governor, advising him daily, traveling with him across the country, managing his campaign committee’s business affairs, and handling the press.
Jason earned his undergraduate degree at Yale University, where he graduated with honors in political science, served as news editor for the Yale Daily News, and played varsity and junior varsity tennis for parts of his college career. At New York University School of Law, Jason was article and note editor for the Journal of Legislation and Public Policy and received the Newman Prize for the most outstanding note.
