Welcome to Dallas Polygraph Services...



The strength of a polygraph examination has proven to be its utility as a valuable tool in on-going investigations. The purpose of a professional polygraph examination is to verify the truth of a specific statement. For decades the Department of Defense Polygraph Institute (DoDPI) has also devoted millions to the research and development of a more effective polygraph methodology for use in national security investigations. Part of this on-going research and studies from the John Hopkins University, Applied Science Labs, resulted in computer polygraph evaluation software.
