Thank you David! If you need a polygraph performed, i 100% recommend this place! We had a fidelity polygraph done in the past and it was a waste of money, but this was worth every penny. David explained everything thoroughly and took his time to make sure we didn’t have any questions before taking it. He also gave us great marriage advice after taking it and i believe this whole experience strengthened our marriage. Thank you again!

David was very straight forward, very nice, and explained everything in a very comprehensive way. This was my first time and he really helped get rid of some the general nervousness I felt when I first got there. 10 out of 10, never want to take a polygraph again unless it's with David.

I was accused of some allegations dealing with my daughter. I came in nervous not really knowing what to expect. I haven’t seen my kids in 9 months , and David cleared my name. He went over everything and explained the process where I was lost and confused . If you are ever needing a polygraph David is the person to go to .
