Business Intelligence & Investigations Department

Founded by Dan Nardello, a highly respected former federal prosecutor, Nardello & Co. operates out of offices in New York, Atlanta and Washington, DC. The firm has a significant litigation support practice, alongside offering assistance with anti-corruption and fraud investigations and due diligence matters. "They are the pre-eminent firm in the US market," says an industry insider. "We introduce them to our most important clients."

The firm's familiarity with the legal profession is considered a distinguishing feature of the organisation. "They're sophisticated players," one interviewee remarks: "Dan hires people who have a view of what the criminal justice system is actually like." One client reveals they "can always trust Nardello to handle things professionally and discreetly. They are the best for complex issues."
