    Human Resources Manager

    "[The PST] staff are incredibly customer service oriented and are extremely proactive regarding the services they provide. They are professional, expedient, responsive and are experts in their field. I have the utmost confidence in all of the services they provide.


    The background investigators they employ are very personable, experienced, professional, knowledgeable, and thorough in their investigations. They keep us apprised of any abnormalities or areas of concern as the investigation progresses and are very willing to do additional research or follow-up if we determine we need more information.


    I never have to question the integrity or credibility of Public Safety Testing, and we have had some unique situations that could have easily provided opportunities for such issues. PST has never disappointed in regard to transparency, while providing us the highest level of confidentiality. They are respectful to our candidates and do not shy away from asking difficult questions. They consistently provide us objective, verified and well documented information in an extremely consistent format that enables us to make the best decisions possible."
