I hired Mr. Dan Seiler to perform a polygraph test for me concerning marital infidelity. We had two telephone conferences detailing the specific information needed. I am sure this information was not anything unusual for him to obtain. He did not ask carry out his promised questioning and refused to answer emails and phone calls. If he was truly professional and a truthful person, it would be a required practice of his to provide his clients with a contract detailing what was my requested information and how to proceed to obtain this information. The only information that he addressed in the correct manner was my credit card number. Each of his circumstances are unique and unique attention to different information. I did not receive this from Mr. Seiler at all. I would never never recommend him to anyone and specifically in such a personal and trusted situation that his business calls for. Go some where else.
