I've been relying on Mike and his staff for doing the pre-employment background checks for a few years now. They have yet to let me down. They've found some stunningly awful things in the history of a few people I would never have thought twice about.

I knew what she was up to but i didn't want to face it. And I really did not want to hear all the denials I didn't believe anymore. You did the work for me and allowed me to just move on and move up. Cheers Mike.

But do some Thai girls have several boyfriends at a time? Do some Thai girls, especially “Bar Girls” continue to see their “former” customers on the side? Yes, of course. These things do happen.

Do some married men pay for companionship while in The Land of Smiles? Of course, some do. 

Thailand would not have the reputation it has if sex were not a significant part of the experience here. So, if you are contemplating contacting our office, among the first questions we will likely ask is “what brings you to the offices of Thailand investigators or private detectives ?

” In other words, do you have doubts? It’s ok, many of us have. Have you noticed curious behavior lately that you don’t quite understand?

We know how that feels. It sometimes turns out to be nothing. But other cases don’t always turn out like you might hope.

What we can offer you is peace of mind. You can trust your Thai girlfriendor your husband. But if you have those nagging doubts, there may well be something to them. And we are here to give you what you deserve: rock solid, documented, factual information so that you can know if your trust is well placed.

 Now it is no more true that all Thai businessmen are always out looking to defraud their foreign partners than it’s true that all Thai Girls are incapable of being faithful. But the fact is, fraud and other white-collar criminal acts are committed in Thailand on a disturbingly frequent basis

So, before you invest your life savings in that dream retirement home, or in that “can’t lose” start-up enterprise you’ve been lucky enough to hear about, why not do the simple and prudent thing, first? Let us take on your due-diligence obligations and let you know if you’re making the right move.

This is again where our vast network of close, long standing relationships with current and former police officials, trusted men and women of business, and even former and current public officials are put to work for your peace of mind and for the safeguarding of your financial assets.

Need to do some hiring?

Maybe even bring in some expert consultants from abroad?

Our efficient but exhaustive methods of performing background checks go way beyond merely contacting the list of references that the prospective employee provided himself. 

And nor do we simply rely on paid online services. Our proprietary, multi-methods approach is tailored to the specific circumstances of your background investigative needs.

 We will deliver you the whole story of the person you’re thinking about hiring: financial status, criminal history, past employment performance. You name it, it’s a part of our report. You deserve nothing less.
