Gregory Morvillo, a partner in the New York office, is perhaps best known for his work shaping insider trading law.  His victory before the Second Circuit Court of Appeals in the landmark insider trading case United States v. Newman propelled him to being one of the most sought after insider trading defense attorneys in the country.  He represented Anthony Chiasson in the criminal, appellate and regulatory actions in that case, all of which resulted in total exoneration.  His work for Chiasson led a national publication to note that he “went toe-to-toe with hard-charging U.S. Attorney Preet Bharara to win a landmark Second Circuit decision … that raised the bar for prosecuting individuals who are one or more layers removed from sources of confidential information and overturned the conviction of his hedge fund manager client.”

In the wake of Newman, Greg has become immersed in insider trading and securities fraud cases.  He has tried multiple insider trading/securities fraud cases to verdict since opening Morvillo LLP, and has taken on multiple appeals for clients in this ever-evolving area of the law.  He also regularly advises public companies and privately-owned hedge funds on their compliance issues and methods to train/educate employees to avoid running afoul of the law.  He has written and spoken on insider trading and corporate best practices dozens of times in the past few years. 

Beyond his insider trading work, Greg has represented both individuals and corporations in dozens of federal and state court actions and in government investigations.  He has litigated against United States Attorneys’ Offices across the country, the Department of Justice in Washington, D.C., various regional offices of the Securities and Exchange Commission, the New York State Attorney General’s Office, the Manhattan District Attorney’s Office, the New York Stock Exchange, FINRA, and other government and self-regulatory organizations. He also has advised clients on criminal law, securities, regulatory, civil, administrative, and corporate governance issues.

Greg has been consistently honored by being named to the International Who's Who of Business Crime Defence Lawyers in 2012, 2013, 2014, and 2015.  He has twice been named to InterContinental Finance Magazine’s Leading Lawyer 500 list, that rates the top 500 lawyers in the world today. Greg was recognized as a Super Lawyer in Super Lawyer Magazine’s 2012, 2013, 2014, and 2015 editions. He was named as one of seven “Rising Stars” in the Criminal Defense: White Collar Practice area in Super Lawyers Magazine in 2011.
