Lee Bergstein

Life-long Litigator, Storyteller at Heart

Lee Bergstein was a city and state prosecutor for almost nine years before starting Bergstein Flynn and Knowlton PLLC. During his time at the New York State Office of the Attorney General (OAG), Lee was assigned to the Criminal Enforcement and Financial Crimes Bureau, where he led complex white collar investigations including:

  • Securities fraud
  • Ponzi schemes
  • Stock market manipulation
  • Residential mortgage fraud
  • Whistleblower investigations
  • Insurance fraud

While at the OAG, Lee worked closely with other bureaus to tackle complex issues which required an intimate understanding of both the civil and criminal white collar landscape. He was an early member of a real estate task force that identified and investigated developers, landlords, attorneys, title companies, and other individuals or entities who conspired to defraud banks, government entities, and unsuspecting homeowners. Lee was also a member of the trial team that prosecuted and convicted a network of individuals who defrauded nursing students.  

Prior to his time at the Attorney General, Lee worked for over six years at the Queens County District Attorney’s Office where he handled the prosecution of countless violent and nonviolent crimes including:

  • Attempted Murder
  • Robbery and Burglary
  • DWI and DUI
  • Drug Cases
  • Grand Larceny
  • Fraud and other Economic Crimes

Lee has tried dozens of criminal cases to verdict and negotiated hundreds to plea settlement. A self-described life-long litigator and trial advocacy instructor, his philosophy: “I love being in a courtroom and working towards my client’s goals through advocacy but  what I enjoy even more is using that experience to view each and every business decision through the prism of potential litigation, to avoid the cost and aggravation of it for my clients. But, it helps knowing that if the worst occurs, and we have to litigate, they are in good hands.”

In addition to his litigation experience, Lee has taught and tutored prospective lawyers for many years. From 2011 through 2014, he served as an Adjunct Professor of Law for Trial Advocacy at the Hofstra University School of Law. More recently, he served as a guest instructor of Trial Advocacy at Columbia Law School.

Lee is committed to superb customer service, diligent attention to detail and optimizing technology for his clients’ benefit both inside and outside of the courtroom.
