Office of Professional Standards

It is the policy of the Lake County Sheriff’s Office to receive and investigate all complaints involving allegations of misconduct or unsatisfactory performance by members of the Sheriff's Office. The Office of Professional Standards conducts criminal or administrative investigations relative to respective allegations in a professional, objective and expeditious manner for prompt corrective action and to ensure continued public trust in the Sheriff's Office.

The investigations also serve to protect members of the Sheriff's Office from unwarranted allegations pursuant to the performance of official duties.

In 2018, Sheriff John Idleburg expanded the Office of Professional Standards.  This was done to ensure we are holding ourselves accountable.  Sheriff Idleburg believes it is an absolute must that we are accountable to the community.
