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.

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 is Professional, Fast, Effective I'd tried various online data sources to track down someone who had agreed that he owed me a mid-five-figure sum, and then disappeared. NAI found his new location in one day- a gated situation, so serving papers on him may be difficult. NAI has been a helpful advisor in discussing next steps.

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.

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!
