The Office of the Sheriff is currently seeking qualified individuals for the challenging position of Reserve Deputy Sheriff.

Since 1951, Reserve Deputy's have provided the Office of the Sheriff and the communities they serve with thousands of hours of professional service. The members of the Sheriff's Reserve Program are citizen-volunteers who give their time to increase the safety and security of their community.

On Going Training Program

As part of the Sheriff's commitment to the Reserve Program, it is our intent to provide all levels of Reserve Training to our volunteers.

Reserve Deputies are eligible to attend the same training courses offered to the full-time employees of the organization.    

Police equipment and uniforms are provided to the volunteer by the Office of the Sheriff. Sheriff's Reserve Deputies receive an annual uniform allowance for the maintenance of issued equipment and uniforms.
