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

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.

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!

NAI Made Game-Changing Discoveries On My Behalf I needed a PI to investigate a sensitive matter I had a hunch was not as it seemed. NAI's intel upon conducting a thorough background check completed transformed my view of the situation allowing me to assess my options with clarity. The information he discovered was game-changing for me. I highly recommend NAI to others in need of PI services.
