The Best There will never be enough words or the right words to express my gratitude. I dealt with Darrin who was always available to work with me regarding my husband's infidelity. Darrin had compassion and empathy while helping me thru this terrible time. I felt very lost and Darrin helped me see what was going on. If it weren't for him and his team I would be stuck feeling like I'm crazy and paranoid but now I know the truth. I'm forever grateful and would recommend this company to anyone who had any doubts about their personal life.

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!

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!

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.

Nothing but the best...! I was caught in an unfair situation after many years of trust in a marriage being broken. I spoke with Darrin Giglio several times and used his many years of knowledge and expertise for surveillance. Darrin Is a true professional and is available throughout the investigation. I leaned on Darrin and his team several times, in sporadic and contiguous surveillance. Locally and afar, in my case nothing was found but each time information was sent over in real time. My issue has been put to rest for now, but I will lean on Darrin again in the future. Thanks for handling a sensitive matter professionally with discretion. I thoroughly recommend Darrin and NAI.
