OUR GOAL

Our goal has always been to provide our clients with accurate information. Every test we conduct is done so in a professional manner by a certified polygraph examiner. We proudly employ up-to-date techniques and industry-leading computerized instruments.

THE OWNER

David Otwell, owner and operator of Truth Verification Polygraph Services, has over 30 years of law enforcement experience. During that time, he served as a commissioned officer in local, state and federal law enforcement positions. He is presently serving as a federal law enforcement officer in the Oklahoma City metropolitan area where he conducts national security investigations and criminal polygraph examinations. Otwell was trained in the use of polygraph by world-renowned polygraph examiner Cleve Backster of Backster School of Lie Detection in San Diego, California.*

*In 1948, Cleve Backster accepted a position as an interrogation specialist with the Central Intelligence Agency, where he instituted their still-active polygraph program in 1949. In 1962, Backster founded the Backster School of Lie Detection, the generally recognized leader in establishing and teaching polygraph technique standards. He has served as a training director for more than 177 basic polygraph examiner training courses and scores of advanced polygraph examiner work conferences and seminars. Unlike other polygraph schools, students come from all over the world to learn from Backster.
