Nola Heller, a unit chief at the U.S. attorney's office for the Southern District of New York, is leaving in June to become a white-collar crime and government investigations partner at Cahill Gordon & Reindel.

Heller, who has served in the Southern District office for 11 years, has been chief of the violent and organized crime unit since August 2015. Before that, she was chief of the general crimes unit. Heller, 38, has prosecuted or supervised more than 2,000 cases involving racketeering, securities fraud, money laundering, bank and wire fraud, tax fraud and cybercrime, the firm said in announcing her hire.

The centerpiece of her work as a line prosecutor were many large scale racketeering cases involving violent gangs in the Bronx and Manhattan, she said. In her role as a unit chief, Heller supervised the racketeering, health care and securities fraud trial against Michael Danilovich in what the U.S. Attorney's office called the largest no fault insurance fraud scheme ever charged.
