Bill
Yamber has served as a deputy sheriff for the Orange County Sheriff’s

paratrooper in the U.S. Army’s 82nd Airborne Division.
The majority of

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.
