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!

FANTASTIC! FANTASTIC!! I had a difficult situation that I turned to Darrin Giglio at NAI for help. From the first time I contacted them, they were helpful and professional. Pricing was always put in writing and was transparent. Communication was stellar and follow-up was terrific. They got the job done and made sure to fill out the paperwork I needed to move forward. On a personal note, they followed through and checked up on me throughout the process. Darrin Giglio was efficient, thorough and kind to me at this difficult time. I cannot recommend them enough and Darrin in particular

Exceptional Service North American Investigations were very kind and sincere, asked me all the questions pertaining to the service I needed. Very reasonably priced. I got my results within 3 days and it was very detailed and I could tell by the results they sent me, what they found out was very accurate, they gave me information in the report that I had forgotten to tell them. Absolutely Outstanding Company I would Highly recommend this company whatever your needs may be. 3-2016

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.
