First Class Service NAI and Darrin are first class all the way. Unfortunately, had to do some surveillance and came across Darrin's reviews. From the moment I spoke on the phone with Darrin, I had a great comfort level and knew the job would get done properly. Attention to detail and thoughtfulness of questions and background information all very precise and timely accurate reporting. I could not recommend Darrin and NAI more, and will use them again if need be! Thank you!

Nothing but the best...! I was caught in an unfair situation after many years of trust in a marriage being broken. I spoke with Darrin Giglio several times and used his many years of knowledge and expertise for surveillance. Darrin Is a true professional and is available throughout the investigation. I leaned on Darrin and his team several times, in sporadic and contiguous surveillance. Locally and afar, in my case nothing was found but each time information was sent over in real time. My issue has been put to rest for now, but I will lean on Darrin again in the future. Thanks for handling a sensitive matter professionally with discretion. I thoroughly recommend Darrin and NAI.

Best decision I've made in a long time I spent weeks trying to find certain information online but to no avail. I chose to hire Darrin and within 2 days he found everything I was looking for. It was a pleasure working with him. I never felt uncomfortable or judged. In fact he was understanding and supportive through the entire process. I fully 1000% recommend Darrin and North American Investigators. Their price was more then reasonable, he was very professional, and bottom line is he did everything I asked him to do. I could not be any happier. If you have a need for a Private Investigator, you can and should trust Darrin and his firm.

I had struggled for months to track… I had struggled for months to track down a person critical to the research I am conducting for a book. I found North America Investigators online and called their 800 number. Darrin answered and dealt with my query clearly and efficiently. I received the person's contact details within a couple of days. I was very impressed!

NAI Made Game-Changing Discoveries On My Behalf I needed a PI to investigate a sensitive matter I had a hunch was not as it seemed. NAI's intel upon conducting a thorough background check completed transformed my view of the situation allowing me to assess my options with clarity. The information he discovered was game-changing for me. I highly recommend NAI to others in need of PI services.
