Mission Statement

"To provide the most current and effective training programs available for investigators, which are based upon solid academic research and practical, effective application within the field." 

All of our training programs are aimed at improving the investigator's ability to gather and assess information from people in an effective, ethical manner.

It's important to know when someone is lying, both personally and professionally, but it is just as important to know when they are telling the truth. Through our training, you will learn and understand both, which will lead to you the goal of getting the truth from people. That is our goal; to train you to find the truth in every investigative inquiry, which is reflected in our company slogan..."When you need to know the TRUTH, your training should be from LIES!"

About Us

L.I.E.S. Linguistic Interrogation Expert Services was established in 2001 with the vision and commitment to produce professional training programs which develop the skills of investigators to obtain accurate and reliable information from people, which is the primary source of evidence and information obtained during most criminal investigations. Our instructors are highly trained seasoned detectives who share a passion for interview and interrogation, statement analysis, detecting deception and finding the TRUTH.

Our training programs reflect our philosophy that investigators are gatherers of facts and information and should be focused on finding the TRUTH within every investigation. To ensure that you gather the most accurate and reliable information during your investigations, you must make sure your training is the absolute best and that it is supported through academic research as well as effective application within the field.
