Bendiksen & Ball is the oldest private polygraph company in Western Washington, operating continually for almost 50 years in the Pacific Northwest. It was opened in 1974 as "Gillespie Polygraph" by Dewey Gillespie soon after his retirement from the Seattle Police Department. Between 1974 and 1986, Dewey Gillespie operated the business with the help of other retired police examiners.
In 1986, Terry J. Ball bought Gillespie Polygraph upon Dewey Gillespie's final retirement to Arizona. Terry Ball operated the business until 2022 as Ball & Gillespie Polygraph and Terry Ball Polygraph, LLC when he sold the business to Chris Bendiksen. Chris Bendiksen is an experienced polygraph examiner with 17 years of experience in law enforcement. Bendiksen & Ball Polygraph offers professional polygraph services to law enforcement agencies, private attorneys, private businesses, and private citizens.

Our professionally trained examiners and our state-of-the-art equipment guarantee that you will receive the very best polygraph examination at Bendiksen & Ball Polygraph.  Don't settle for a poorly trained, inexperienced, polygraph "operator" who will offer you discounted prices.
When you need "only the very best" call Bendiksen & Ball Polygraph.
