Criminal Cases and Attorney Services

Law Firms and Attorneys use polygraph examinations in the pre-court phase and in civil litigation to determine truth in a client’s case, verify a client’s truthfulness relative to a plea negotiation, to assist in general client control and verification of witness statements.

Is your client telling you the entire truth? Did your client really commit the crime? Are you doing all you can to protect and defend your client? Know the truth. A pre-trial polygraph examination can provide you with the information and answers necessary to defend your client. Our computerized polygraph examinations can be customized to address your specific needs for most criminal, corporate and civil matters.

All examinations and services are strictly confidential and adhere to Attorney-Client Privileges. Examinations are available 7 days per week with accurate and professional reports to use at your discretion usually available the same day.
