Daniel P. Filor, a former Assistant U.S. Attorney for the Southern District of New York, focuses his practice on government investigations, securities and commodities fraud, antitrust law and white collar criminal defense. With both civil and criminal law experience, Daniel counsels clients on a wide variety of matters ranging from criminal fraud allegations to complex commercial litigation.

With more than a decade of experience in the U.S. Attorney’s Office, Daniel uses his understanding of how governmental decision-making works to advise individual and organizational clients confronting criminal and civil allegations of misconduct. While his courtroom advocacy and trial practice is extensive, Daniel also focuses on working with prosecutors and regulators to avoid charges and resolve issues before investigations become public.

His recent work includes white collar defense victories such as persuading the SDNY to dismiss its securities fraud indictment against his client, a public company CFO, in United States v. Pappagallo, and the first-ever acquittal in a commodities “spoofing” trial in United States v. Flotron. Daniel also recently succeeded in having all insider trading charges dismissed against his foreign clients in a high-profile case brought by the U.S. Securities and Exchange Commission. In addition, he represented several individuals and companies in the DOJ Special Counsel’s Office investigation into the 2016 presidential election.
