Decades of Forensic Expertise 

At California Lie Detection, we believe that the technology is only as reliable as the expert behind the console. Our team is not composed of mere technicians, but of seasoned forensic examiners with deep investigative roots in Northern California. By moving beyond the automated approach, we provide a human-centric analysis that accounts for the nuances of human behavior, stress, and communication.

Our examiners bring a “clinical-first” mindset to every session, ensuring that the environment is professional, objective, and most importantly conducive to the truth. Whether we are working out of our Chico, Vallejo, or Redding hubs, our goal is to eliminate the intimidation factor often associated with lie detection, replacing it with a process rooted in forensic discipline.

  • Investigative Intuition: Our team transitions years of law enforcement and private investigative experience into the polygraph and CVSA suite. We know how to ask the right questions to get the right answers.
  • Empathy for Sensitive Cases: We understand that many of our clients are dealing with the trauma of relationship betrayal or domestic trust breaches. We approach these cases with the empathy required to support the individual while maintaining the clinical distance necessary for a valid test.
  • Professional Neutrality: As a trusted partner to the Rooney Law Firm, our examiners maintain a strict standard of neutrality. We are not advocates for a specific outcome; we are advocates for the facts.

When you sit down for an examination with us, you aren’t just being tested by a machine. You are being evaluated by a career professional dedicated to providing a clear, defensible, and honest result.

Polygraph, CVSA, and Statement Analysis

A professional polygraph examiner, accredited by the American Polygraph Association, administers a confidential lie detector test in a modern Chico office. The examiner uses advanced computerized equipment to ensure accurate and discreet results for clients seeking clarity in personal or legal matters

To provide the most reliable truth verification in Northern California, we utilize a multi-disciplinary approach. Rather than a “one-size-fits-all” technology, we offer the three most respected forensic pillars of deception detection.

Strategic Layering for Accuracy

While each method is powerful individually, we often recommend a layered approach. For instance, Forensic Statement Analysis can pinpoint exactly where a subject is being evasive, allowing our examiners to focus Polygraph or CVSA questions on those specific “hot zones.”

Forensic Reliability Standard: All methods utilized by California Lie Detection are validated for private use and are considered forensically reliable for private truth verification. As with all non-polygraph technologies, California Evidence Code 351.1 applies. No method guarantees 100% accuracy.
