All our covert surveillance agents are trained to be highly conscientious, incredibly patient and fast thinking.

Background checks in the US have become increasingly popular over recent years. This is because more and more companies and individuals have realized how valuable the insights that come from these checks are. Whether these checks are completed for personal or business reasons, they can lead to people making smarter and better-informed decisions.  

Missing Person Enquiries

People go missing for a variety of reasons, and although there may not be sinister reasons behind the disappearance, it can still be distressing and problematic.
Contacting the police for missing person enquiries is not always practical, and that’s where Discreet PI Investigations can help.
