We conduct polygraph screening exams for dozens of police and fire departments or commissions for entry level police, fire, dispatchers, records clerks and community service personnel.

For the screening of private sector employees, we conduct polygraph exams for those who can qualify under the Employment Polygraph Protection Act of 1988. We also offer employment interview evaluations for those who do not qualify under the EPPA Act.

We conduct sexual history, instant offense, maintenance and monitoring examinations on those accused of sex crimes as well as convicted sex offenders for a variety of state and county agencies as well as for individuals in voluntary therapy with private counselors.

Also, we conduct testing for private couples struggling with issues of sexual addiction or infidelity in their relationships.

Polygraph examinations are administered by the newest model computerized instrument.  Video and audio recordings are also conducted with examinations.

Our examiners are also certified to administer polygraph examinations to those convicted and accused of sexual crimes.
