I can truly say that I have received a 100% service. Jack took the time to call me. He was polite, courteous and attentive to my needs. The best type of service for my needs and within no more than a few hours I had a full report, if you ever need a private investigating service, I would encourage you to use National Private Investigators. Thank you, Jack and your team.

A very professional experience. We found ourselves in a difficult predicament with a legal matter that required some expert input. Jack provided this efficiently, quickly and was very helpful throughout. I wouldn’t hesitate to recommend. Thanks very much.
