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!

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.

Photographic survalence When I first hired NAI to get pictures Of my alleged daughter I was a nervous Wreck. Would I get a call from my Ex saying there were suspicious looking Men outside her house with cameras. I learned immediately however to Relax Darrin and his team of private Investigators are extremely professional And more important extremely discrete They also do great work I wholeheartedly recommend them Sam

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!

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.
