Global Polygraph & Security

Aug 2022

I have taken a lie detector test in the past, so I am a little bit familiar with the process. No doubt, this examiner is the best. Very thorough procedures, no shortcuts, very professional. His credentials check all the right boxes, and I was very pleased. If you need a polygraph test, that is the guy to go to. Thank you Mr. Gelfer.

Coming into the test, I was very nervous and skeptical. Mr. Gelfer explained to me patiently about the test and the procedure and administered the test very professionally. I highly recommend him to anyone who seeks to find out the truth!
