Leveraging her experience as a veteran federal prosecutor, Kristy Greenberg focuses her practice on complex white collar defense and investigations. She has extensive experience in sophisticated financial crimes, cryptocurrency fraud, health care fraud, cybersecurity, anti-money laundering, tax fraud, FCPA violations, employment discrimination, and sexual misconduct matters.

Prior to joining Hogan Lovells, Kristy served for over a decade in the U.S. Attorney’s Office for the Southern District of New York (“SDNY”), most recently as Deputy Chief of the Criminal Division. As a senior member of SDNY’s management team, Kristy oversaw the work of the Criminal Division, supervising the Securities and Commodities Fraud Task Force, Complex Frauds and Cybercrime Unit, and Money Laundering and Transnational Criminal Enterprises Unit. Kristy also supervised SDNY’s new AUSAs as Acting Co-Chief of the General Crimes Unit and managed large-scale health care fraud cases as SDNY’s Health Care Fraud Coordinator.

Kristy has supervised and prosecuted white collar, cryptocurrency, and cybercrime cases of national significance. She oversaw ground-breaking cryptocurrency and securities fraud cases, including the first ever cryptocurrency insider trading tipping scheme. She also authorized significant corporate FCPA and tax fraud resolutions, including one of the Department of Justice’s largest FCPA resolutions. Kristy was the lead prosecutor on several of SDNY’s most high-profile cases: a $26 million investor fraud by Fyre Festival founder Billy McFarland; a $5 million health care fraud by 24 former professional athletes and medical professionals; and cyber hacking of hundreds of celebrities.

Kristy is an accomplished trial lawyer and appellate advocate. In 2018, she received the “Top Prosecutor” award from the Women in Federal Law Enforcement Foundation.
