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!

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

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.

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

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.
