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!

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.

The Best There will never be enough words or the right words to express my gratitude. I dealt with Darrin who was always available to work with me regarding my husband's infidelity. Darrin had compassion and empathy while helping me thru this terrible time. I felt very lost and Darrin helped me see what was going on. If it weren't for him and his team I would be stuck feeling like I'm crazy and paranoid but now I know the truth. I'm forever grateful and would recommend this company to anyone who had any doubts about their personal life.

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!
