Clayton Polygraph Services, LLC, was founded by David J. Clayton, a former City of Hattiesburg Police Detective with over 28 years of investigative experience. At Clayton Polygraph, we specialize in professional lie detection testing using both Polygraph and EyeDetect technologies, making us the only lie detection service in Mississippi to offer both methods. With over 20 years of experience, we have assisted in testing relationships for betrayal trauma and have been providing reliable testing services for clinical therapists throughout this time. Our agency conducts credibility assessments related to sex addiction, drug use, alcohol use, gambling, and various other compulsive behaviors, typically under the direct involvement of therapists, family, and marriage counselors. We also specialize in preparing couples for full disclosure tests and maintain a network of counseling referrals to support this process.
