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!

5 stars not enough 5 stars not enough, I’ll give them 10. My family and I going through a horrible probate court case, to make a long story short we needed a background investigation on a woman claiming to be a Registered nurse. I called NAI not knowing what to expect. I spoke to Darrin and I know I was nervously rambling on. Darrin was so calm, cool & professional, took some information and 10 days later we had what we needed. Can’t speak enough on how professional Darrin and the staff were.

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!

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!

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
