HLA Polygraph Services offers a professional and efficient service to its government and corporate clients in order to promote honesty, and increase efficiency. This assists in shortening the investigative process, saving time, money and manpower. The Polygraph may also be used for pre-employment or periodic testing. This type of testing eliminates those people who may have been involved in criminal activities at places of previous employment or those who may be involved in unfound activities within present employment.

Examiners have received certified training through the Academy for Scientific Investigative Training and are members of the American Polygraph Association.
