Dan founded the firm in London in 2003, and it has since expanded to New York, its headquarters; Washington, DC; Hong Kong; Dubai; Paris; Singapore; Los Angeles; and San Francisco. He maintains an active presence in the firm’s highest profile matters including activist defense, complex litigation, and special investigations.
Dan has been consistently recognized as a Band 1 leading investigator by Chambers and Partners, which calls him “simply the best,” and continues “[Dan is] dedicated to client objectives…hiring Dan means not worrying about investigations.” Clients quoted in Chambers also note that “he is superb” and “is the best in the field. He’s been involved in so many major matters” and “his experience in large criminal cases is unparalleled.”
Dan is also featured in the Spear’s Business & Entrepreneurship Index for security, intelligence and investigations, ranked as a ‘top recommended’ advisor.
Among his significant public matters, Dan was appointed by the government of Abu Dhabi as the independent investigator of allegations of abusive labor practices in the construction of New York University’s Abu Dhabi campus. Dan was also named as the independent investigator to resolve issues arising from the settlement agreement between the State of New York and leading tobacco manufacturers. Currently, Dan leads the Nardello & Co. team engaged by the new leadership of FTX to investigate, among other things, the circumstances of its collapse and the location of its assets.
Dan has written and spoken on a wide range of topics, including the US Foreign Corrupt Practices Act, defending corporations from activist attacks, vetting board candidates in the #MeToo era, and conducting defense investigations in white collar cases. He created and teaches a New York- and California-certified CLE ethics course entitled Retaining Private Investigators: Ethical Considerations and Concerns.
After working in private practice at Patterson, Belknap, Webb & Tyler, where he represented clients in libel and related matters, criminal investigations, and disciplinary proceedings, Dan served as a federal prosecutor in the US Attorney’s Office for the Southern District of New York, and is an alumnus of that office’s Securities and Commodities Fraud Task Force. In addition to securities cases, Dan prosecuted organized crime, civil rights, and corruption matters. While in the US Attorney’s Office, Dan was an adjunct professor of trial advocacy at Columbia Law School.
After government service, Dan opened and managed the first European office of an international investigative firm. He focused on providing expert litigation support, global asset tracing, fraud investigations, and complex due diligence services for private clients.
Observing that most investigative firms lacked the responsiveness and creativity to meet their clients’ demanding objectives, Dan resolved to fill that need by recruiting an exceptional team of former prosecutors, law enforcement officials, professional investigators, forensic accountants, cybersecurity and computer forensic experts, and researchers.
