Polygraph Examinations

The integrity and quality of a polygraph examination relates directly to the expertise of the Polygraph Examiner.   Our Polygraph Examiner, Doug Brenn, is a graduate of Backster's School of Lie Detection (resume available upon request).  This institution is a nationally recognized training facility for Polygraph Examiners and is approved by the American Polygraph Association (APA).  Doug was trained by Chief Instructor Cleve Backster, the founder of the Central Intelligence Agency's (CIA's) Polygraph Unit. 

We are a member in good standing with the American Polygraph Association.

In the case of Employee Theft Polygraph Examinations, CORE Investigations & Polygraph is fully compliant with the Employee Polygraph Protection Act and California State Labor Code 432.2.  

We utilize a State-of-the-Art Computerized Polygraph Instrument.  We are a mobile polygraph service that will come to your location.  Your results are provided on the "same day" as the examination.  The polygraph examination process is extensive (2 - 3 hours) and compliant with the standards set forth by the APA.
