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!

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!

peace of mind I contacted north american about doing a back ground check on a person who came in contact with my family. I was only able to give them a last name of the person and their most recent address.and in less than 10days they were able to give me the information I needed To feel more confident about my family's safety in regards to this person I would recommend north America to any one .thanking you in advance james J.

NAI and Darren Giglio were amazing! Working with NAI was a great experience. I had never used this type of service before and I was nervous about how to proceed. Darren Giglio, my PI, was excellent. He explained everything in great detail and went above and beyond to help me with my complicated situation. I would definitely recommend Darrin and would work with him again in the future!

5 stars not enough 5 stars not enough, I’ll give them 10. My family and I going through a horrible probate court case, to make a long story short we needed a background investigation on a woman claiming to be a Registered nurse. I called NAI not knowing what to expect. I spoke to Darrin and I know I was nervously rambling on. Darrin was so calm, cool & professional, took some information and 10 days later we had what we needed. Can’t speak enough on how professional Darrin and the staff were.
