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.

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!

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.

Missing person found Darrin recently helped our family to locate a loved one. His team handled the situation in a caring and discreet way. I was amazed at how quickly they succeeded in locating the family member. He returned each call/ email we sent and gave us regular updates. He completed the mission in less than three days. He was very professional, clear in communication and transparent in describing the investigation cost upfront. I highly recommend the services of North American Investigations.--JM

Mine was a missing person case Mine was a missing person case. It was my son. He had been missing and my daughter-in-law only alerted me 3 or 4 days later. Having been in touch with the Suffolk County Police Department in New York, I realized nothing was getting done because my son was an adult. I searched for a private investigator online and found Darrin Giglio and his company. It was the best result. Darrin and his team ended up finding my son’s body and that of another young victim AND was able to determine who was responsible for this heinous murder. All the evidence was then turned over to local law enforcement. The perpetrators were convicted and sentenced. With Darrin’s team, NOTHING would have been done and I would’ve been left with a missing son all these years and the criminals would’ve still been on the streets! Just a last word: my choosing Darrin and his team, in my opinion, was a Godsend!
