Spectrum Polygraph

Spectrum Polygraph provides lie detector exams for relationship, financial, workplace, pre-employment and immigration matters. Common exams cover infidelity suspicion, online activity and sexting, hidden financial dealings, and questions about someone's motives in a relationship or marriage. The company also screens police and public safety applicants and offers polygraph support for couples working with a therapist.

Exams can be given on site at the client's location or at the company's own facility in Hacienda Heights, and appointments can be arranged around a busy schedule. Testing is available in English and Spanish, and an initial consultation is free. Clients come from across Southern California, including Los Angeles, Orange, Riverside and San Bernardino counties.
