ABOUT US
Duven Polygraph Services was established in 2020, after Owner and Polygraph Examiner Eric Duven retired from his career as Support Services Commander at the Aberdeen, South Dakota, Police Department. Prior to his promotion to Captain, Eric served as Detective Sergeant, Detective, and Patrol Officer in his 26 years of service.
​
As a certified forensic psychophysiologist, Eric has administered a myriad of polygraphs since completing his initial certification in 2005. Since then, he has completed additional specialized training and accreditation.
​
Eric's primary focus is to perform accurate, fair, professional, and ethical polygraphs or otherwise called, lie detector tests. His nature is to lead with a positive "bedside manner" to alleviate additional stressors from subjects during examinations.
