Biography and Additional Professional Information

I graduated from the DoDPI (now known as the National Center for Creditability Assessment)forensic polygraph course in November 1992. While working as an examiner for the US Army Counterintelligence program from 1992 to 1994, I attended the Manager Course at DoDPI and participate in the validation study for the Test for Espionage and Sabotage (TES). When I retired for the US Army, I started my own polygraph business. Since 1994, I have administered thousands of examinations for a wide range of clients to include police departments, attorneys, district attorneys, public defenders, insurance companies, school systems, fire departments, clinical therapist, probation departments, businesses of all types and private individuals. I have administered criminal specific examinations, screening examinations and PSCOT examinations. I have been a member of the American Polygraph Association (APA) since 1998. I am also a member of both the Tennessee and Kentucky Polygraph Associations. My professional education is current as I regularly attend continuing education seminars sponsored by the APA and by reading all published polygraph journals. I am licensed in both Tennessee and Kentucky. I am PSCOT certified and on the approved list of PSCOT examiners in both Tennessee and Kentucky.
