Baker & Associates

Baker & Associates was established in 1975 and grew to become the Plains States’ most respected corporate investigative and loss prevention firm. Baker specialized in conducting legal investigations, truth verification examinations, vetting & psychological screening for law enforcement & nuclear power generating facilities, and labor / anti-racketeering consulting. E. Gary Baker was a pioneer in Voice Stress Analysis development, working closely with the three inventors and early examiners in the 1970’s.
