The Probation Department operates adult and juvenile Court-related services in the areas of investigation and supervision. When probation is granted, the Department is responsible for the supervision of the probationer and enforcement of the conditions and terms of probation. The Department is also responsible for the overall operation of the County's Juvenile Hall, which provides custody, counseling, medical care and guidance of delinquent and custodial children in a variety of short- and medium-term programs.

The core values of the department that will assist us in our mission are:
