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!

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.

Darrin Darrin Thank you for helping to resolve a difficult family situation so quickly and professionally. You helped to save a life. We are so thankful to you and your staff at NAI. Darrin was wonderful to deal with. Answered all questions and was always available. Highly recommend Darrin and his staff with any investigation services needed. RJM

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.

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!
