General Info

Testing sites in Sacramento and Redding... BACKGROUND: Douglas Mansfield and Jeff Lierly have a combined 80+ years of experience in the fields of law enforcement and polygraph. We are certified PCSOT (Post Conviction Sex Offender Testing) examiners and are actively engaged in testing for several law enforcement agencies, federal and county probation, sex offender therapists, and the private sector. We specialize in all types of polygraph examinations, including Law Enforcement Pre-employment, Post-conviction Sex Offender Testing (PCSOT), Criminal Investigation (Law Enforcement/Prosecutors/Defense Attorneys), and all types of private testing (infidelity, sex abuse, theft, drug use, etc.). We also specialize in testing individuals who are trying to prove to others, they did not do the thing they were accused of having done, usually a sex abuse allegation. EYEDETECT: We are also pleased to announce that we are the only Credibility Assessment Professional firm in the Northern California to offer EyeDetect testing. EyeDetect testing involves answering simple T/F questions about the issue without having multiple components connected to your person. It takes about 20-30 minutes and it has a scientifically tested accuracy comparable to polygraph accuracy. Unlike polygraph, EyeDetect is an objective analysis scored by computer algorithm and the results cannot be affected by the test administrator. For additional information, please call me at 916.710.1030, or go to www.converus.com. ATTORNEYS: To obtain the highest level of confidence in the final outcome, I typically conduct dual testing using both polygraph and EyeDetect. When both tests are in concordance, there is about a 98% probability that, using the two independent deception detection methodologies, the correct decision (truthful or deceptive) was reached.
