I called me. Nibbling on Tuesday evening and had an appointment Wednesday at 4pm. I had called several polygraph testing centers and to my surprise people were very rude. I had a list of questions I wanted Mr. Nibbling to ask my husband he explained to me which questions I could ask and which questions might alter my results. Mr. Nibbling was very professional and very kind and sympathetic to our situation. Not to mention very reasonably priced. Hopefully I wont be needing Mr. Nibbling’s services again anytime soon but if I do I would definitely go back by the way my husband passed with flying colors. give them a call you will not be disappointed .
