Our Core Lie Detection Services

1. Polygraph Examinations (In-Person)

The gold standard for biometric truth verification. Our examiners use state-of-the-art computerized polygraphs to monitor physiological indicators of deception.

  • Best For: Legal defense, criminal allegations, and deep-dive infidelity cases.
  • Location: Available at our offices in Chico, Vallejo, and Redding.

2. CVSA – Computer Voice Stress Analyzer

A non-invasive, voice-based risk assessment tool. CVSA is an additional layer of forensic analysis that measures micro-tremors in the human voice.

  • Best For: Remote testing and initial screenings.
  • Note: Validated for private use as a forensically reliable tool for private truth verification.

3. Statement Analysis & Scan

A specialized forensic technique used to analyze the linguistic structure of written or verbal statements. We identify “gaps” in narratives where information is being withheld.

  • Best For: Pre-test screening and evaluating witness statements in legal cases.

Specialized Case Directories

Infidelity & Relationship Betrayal

If you are in a relationship where trust has broken down, the question isn’t whether your partner is lying, it’s how to know for certain. We handle these cases with extreme empathy, providing a neutral, professional environment in Chico or Vallejo to help couples find a path forward.

Legal & Attorney Services

We assist defense teams in Redding and Yuba City by providing objective data for “investigative impasses.” Our results help attorneys exonerate the innocent or verify client statements before trial.

  • Disclaimer: As with all non‑polygraph technologies, California Evidence Code 351.1 applies. No method guarantees 100% accuracy.

Corporate & Workplace Integrity

Protect your assets with our single-umbrella corporate services. We handle internal theft, embezzlement investigations, and executive vetting for businesses across Northern California.

Frequently Asked Questions

How much does a lie detector test cost in Northern California?

Standard in-person polygraph exams start at $500, while CVSA/Voice Stress sessions start at $400. This price may be different depending on the nature of the case.

Can I get a test done today in Vallejo or Redding?

We prioritize urgent cases. While we recommend 24-hour notice, we often have same-day availability at our primary geo-anchors in Vallejo, Redding, and Chico.

Is the CVSA as accurate as a Polygraph?

The CVSA is a voice-based risk assessment tool validated for private use. It is often preferred for its non-invasive nature and remote capability, whereas the polygraph is the standard for high-stakes legal biometrics.

Do you serve Southern California?

No. We focus exclusively on Northern California (Chico, Redding, Vallejo, Yuba City, and Sacramento) to ensure the highest level of local expertise and response time.

What happens if the person refuses to sit for the test?

A lie detector test is voluntary. However, a refusal often provides its own kind of clarity in private investigations. We can consult with you on how to best approach the subject.
