Advisory Committee Members

The POST Advisory Committee performs a key role as part of the Commission’s team by providing a two-way communication link between the Commission and organizations that share an interest in the Commission’s work.  The committee meets prior to each Commission meeting to review and analyze topics the Commission will later address.  Advisory Committee members represent associations and organizations within the California law enforcement community, educators, and the public-at-large.  Therefore, they provide valuable input on many contemporary and evolving issues in law enforcement, helping the Commission and POST better serve California's peace officers and the citizens they protect.   Appointed by the Commission for a term of three-years, Committee members receive no compensation but they are reimbursed for their expenses for attending meetings.
