I could not have made a better choice than Northern Virginia Pre-Employment & Po

I could not have made a better choice than Northern Virginia Pre-Employment & Polygraph Services. Darryl DeBow, the respected owner-operator, could not have been more helpful. Faced with utterly false workplace accusations, the documentation Darryl was able to provide convincingly showed that I was truthful, and, therefore, others were at the best badly mistaken. This made all the difference for me! I cannot thank Darryl enough.

While I don't know if my wife will ever trust me again, taking the step of doing

While I don't know if my wife will ever trust me again, taking the step of doing a poly felt like the right thing. Brennan explained the process and made me feel less nervous about it. Darryl did his best to keep me at ease during testing but with my marriage at Stake that wasn't really going to happen even though I knew I wasn't going to lie. Ultimately I passed, and although it may not convince my wife to trust me it certainly isn't because of any failure by the staff here. Customer Service 5 star, Staff conduct before and after exam 5 star, they went above and beyond. I even asked them to email the results directly to my wife since I knew she would claim that I manipulated the document. If you have to take a Poly you may as well take one from someone who has been doing it for years and runs the Virginia School of Polygraph. Only thing I would do differently is I would have asked if they could write up a document dictating how polygraph isn't like the movies and cannot be manipulated. if I had asked that they send that with the results I'm sure they would have obliged.
