 Bill Yamber has served as a deputy sheriff for the Orange County Sheriff’s Office (Florida) (OCSO) the past  28 years. Prior, he served as a paratrooper in the U.S. Army’s 82nd Airborne Division. The majority of his career at OCSO he has been assigned to the criminal investigations division. In 1998 Detective Yamber was selected to attend the basic examiners course and be came a certified examiner. In 2000, in large part due to repeated success with the CVSA,  Detective Yamber was transferred to the human resources division and is now the supervisor of what is arguably one of the busiest CVSA units in the country. The OCSO requires every applicant to submit to a CVSA exam. During 2007 over 900 examinations were conducted. The numbers for 2008 will be closer to 1,000. The OCSO has over 2,300 employees and the hiring process never stops. It is impossible to measure the dollars save through the use of the CVSA but it must be staggering. The reputation of the OCSO’s CVSA unit is believed to be directly responsible for a consistent applicant “no show” rate of 30%. If you had something to hide, would want to go up against OCSO  detectives armed  with state of the art equipment from NITV. Bill has personally conducted over 1,500 CVSA examinations.
