Charles Griffin Intelligence was founded in 2009 by Philip Segal, a New York attorney and expert on complex international financial transactions. Based at historic Rockefeller Center in New York, Charles Griffin is dedicated to ethical fact-finding.

If lawyers, companies or individuals need hard-to-find facts relating to due diligence or litigation, they ask us. Unlike some investigative firms, Charles Griffin is staffed only by lawyers who have the same ethical restrictions on what they can do as our attorney clients.
