Mid Valley Polygraph Information

My name is Dennis Cates and I own Mid Valley Polygraph, located in Tulare County. I am a retired police officer, polygraph examiner, and a graduate of the Marston Polygraph Academy, which is the only APA certified and accredited polygraph academy in the Western United States. I regularly attend certified training seminars to keep myself up to date on the latest scientific information on polygraph testing, and I adhere to the APA’s published documents regarding Standards and Practices of polygraph examiners. I have been trained, and I am proficient in numerous testing formats to include, AFMGQT, DLST, Federal You Phase and Utah Zone Testing. Not only am I trained in these testing formats and the scoring of these particular tests, but I also use industry approved Quality Control Measures to verify my test results.
