Perfect! Did not know what to expect as not in the business of having to serve folks court papers. Mario found me in a way, I contacted him, do this and that. Meet you at the house, this is the price, I meet him, he serves the papers as I watch, and then gives me a monetary reduction of the price because of myself and he being Veterans. could not have been more pleased with the service. Mario, among other services he provides, is a Private Detective whereas I will use his service in the future to locate an individual that might have absconded owing monies so that garnishment of wages: if required, can be obtained. All good!

I have used John and JB National a number of times for a variety of investigations work, from background checks to asset searches to locating hard-to-find people. In a busy law practice, having a solid and experienced investigator is a must in this day and age. I can recommend John for his professionalism and experience, but more than that he is easy to work with and understands the importance of a team approach. John is always willing to modify his services to meet my needs, or the needs of my clients. His positive attitude and good humor go a long way to help in what is often a very stressful situation. Through it all, he remains a consummate professional, and always delivers what he promises, when he promises it. When you need an investigator, give John a call. You won't be disappointed.

I'm very good at finding out things that you cannot. I have found men cheating on women and also found loved ones who decide not to go home for weeks. I have found where people live when others can't. You name it. If you are looking to find out anything about loved ones, friends, or business partners, then, I'm the one for you.
