Meet the Examiner

William (Bill) Holloman

I am a polygraph examiner with 26 years of global experience. I have conducted thousands of
examinations in all aspects of State, Local, and Federal investigations. Major theft, homicide, serious assaults, white collar crime, and sex offenses. I have had the opportunity to travel all over the U.S., the Middle East, Central America, Africa, and various locations in Europe to conduct polygraph examinations related to criminal investigations as well as intelligence matters. My training and experience as a Special Agent with the Federal Bureau of Investigation has given me a wide range of exposure to all types of criminal and intelligence related issues. I have spent years working in concert with other federal, state, and local agencies in a wide variety of investigative matters. 

​I have conducted polygraph examinations related to both World Trade Center attacks, the Amerithrax investigation, and the bombing of the US Embassy bombing in Kenya.

​I believe that the reliability of any polygraph examination is always proportionate to the expertise of the examiner conducting the examination. For this reason, it is extremely important to use caution when selecting an examiner. Feel free to contact me with any questions, and I will be happy to be of service.

I have conducted polygraph examinations for the following listed Federal agencies: FBI, DEA, DIA, CIA, ATF , Secret Service, and the US State Department. I have also conducted polygraph examinations for numerous state and local law enforcement agencies.
