Our Approach
The truth should be holistic and human.
We developed a reputation for accurate polygraph examinations and detailed reports, but we’re also known for putting the examinee in a place to tell the truth without trauma. This is a place where examinees feel open and ready to share. We allow enough time to clarify issues, establish the truth, and review the polygraph test questions, so there are no surprises in the testing phase. The goal of the polygraph examination is to affirm the truth, not break down the examinee. For more information about approach, see the book Polygraph for Relational and Sexual Issues, or the pages About Us and Frequently Asked Questions.
We’re just as committed to the person as the truth.
DO Polygraph, Inc. excels in building examinations that help put the examinee in a place to tell the whole story, with the examiner offering empathetic and attentive focus. Examinees can terminate the test at any time. Breaks are provided to ensure examinee comfort. If significant physiological responses appear during the testing phase, the examinee has a chance to explain those responses. If you’re ready to book, go to our scheduling page and make an appointment.
