NAI Consistently Delivers


I am an intellectual property lawyer specializing in franchise and trademark matters. I have been using North American Investigators exclusively for over eight years in trademark infringement cases, and the investigators there have consistently delivered the evidence I needed to win at trial. More importantly, if a matter needs special or immediate attention, I have always been able to speak directly with the owner, Darrin Giglio, and he has on many occasions done whatever was necessary to accommodate me. I highly recommend North American Investigations.
