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!

Great experience This was a surreal experience for me - something I thought I'd never find myself doing. John was so great to work with - he made me feel so comfortable, got me the info I needed quickly and checked in after to see how the situation was resolved. Hoping I never need him again (don't take it personally John!!), but if I do I know where I'm going!

Accomplished Darrin, was very friendly & answered my calls during all times / weekends as well. He contacted me the following day in regards what they had discovered about my "mystery guy "R". Thanks.

Professional, thorough and quick! I can't stress enough how important using an experienced investigation company is. I had a bad experience with another P.I. firm and Darrin and his team immediately started on my case, they provided me daily updates and sent me the reports very quickly. I am very impressed and would definitely use them again if needed. I highly recommend them and am very satisfied. They are truly the best out there.

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!
