Our office has over 75 years of combined law enforcement and military experience. Each administrator has completed the ten week polygraph school that is accredited through the American Polygraph Association. Our administrators are also PSCOT certified. 

Unlike many other companies, Sentry Service Polygraph is not a referral company.  When you contact Sentry Service Polygraph, we will respond to your phone call, text or e-mail directly.  All testing is conducted confidentially either in a private office setting or at your location with our mobile equipment.
