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!

FANTASTIC! FANTASTIC!! I had a difficult situation that I turned to Darrin Giglio at NAI for help. From the first time I contacted them, they were helpful and professional. Pricing was always put in writing and was transparent. Communication was stellar and follow-up was terrific. They got the job done and made sure to fill out the paperwork I needed to move forward. On a personal note, they followed through and checked up on me throughout the process. Darrin Giglio was efficient, thorough and kind to me at this difficult time. I cannot recommend them enough and Darrin in particular

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!

Best decision I've made in a long time I spent weeks trying to find certain information online but to no avail. I chose to hire Darrin and within 2 days he found everything I was looking for. It was a pleasure working with him. I never felt uncomfortable or judged. In fact he was understanding and supportive through the entire process. I fully 1000% recommend Darrin and North American Investigators. Their price was more then reasonable, he was very professional, and bottom line is he did everything I asked him to do. I could not be any happier. If you have a need for a Private Investigator, you can and should trust Darrin and his firm.

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
