Investigations & Surveillance

Get the Clear Facts


Our investigators are skilled in numerous surveillance scenarios and have proven thorough, efficient, and discreet in extracting useful information. Are you experiencing familial issues? Perhaps you know something is not right, but you need help finding evidence. A seasoned private investigator can work with you to amass the evidence you need in order to protect yourself, your child, and your family. Although PIs are not police officers, they often have a criminal justice background. Private eyes have been known to cite background checks for a majority of their credible findings. Joe Mar Polygraph & Investigations is prepared to gather the evidence on your behalf (background checks and otherwise) and deliver clear facts to you.
