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.

Why have even one star Why have even one star, as I would not give him even one star... Was very vigilante about getting my $750 retainer initial payment, very little communication or follow up. He will not say 'what' he has done...private??? I think not he has simply not done anything...so has nothing to say to me, other than he needs/wants more $$$$. Save your money....when he told me 'I am an honest man' I should have listened no honest man needs to make that claim

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 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!

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.
