Polygraph testing, often referred to as a lie detector test, is a pivotal tool in determining the truthfulness of information or statements in virtually any situation that requires knowledge of the truth.  Physiological Detection of Deception (PDD) involves rigorous protocols to deliver a qualified opinion to specific or multiple issues. 

A properly trained and competent polygraph examiner will conduct a legal and proper polygraph test utilizing calibrated scientific instruments and validated testing techniques.  Only through these means will you receive a reliable and credible opinion of a subject’s truthfulness.  PDD has consistently produced information, which was impossible to obtain through other means. 

The examiner is a member of professional polygraph organizations, and strictly adheres to American Society for Testing and Materials International (ASTM) Polygraph Standards of Practice and American Polygraph Association (APA) professional procedures and ethics.
