In these matters, 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, and other government and self-regulatory organizations. During this time, he has advised clients on criminal law, securities, regulatory, civil, administrative, and corporate governance issues. Greg also has participated in both criminal and SEC trials, including his work as a key member of Martha Stewart’s criminal and SEC defense team.
