Truth Lab opened its doors in 2007 in Dewey, Arizona, and added a second office in Phoenix in 2009.  Now she has a office in Tempe, Arizona only. The examiner, Laurie Peschke, is fully qualified to administer all types of polygraph exams. She graduated from Arizona School of Polygraph, an accredited school.

She received two certificates from the American Polygraph Association: the Certification for Advanced and Specialized Training, and Qualification for Post Conviction Sex Offender Testing.

Ms. Peschke has a Bachelor’s and Master’s Degree in Social Work from George Williams College of Aurora University.  She worked for years as a medical social worker in Chicago and Arizona and as a Therapist in Chicago in her own practice.  Her background of working one on one with people has proven useful in her polygraph examinations.
