Lake County Sheriff Squad and Mark Curran

Respected Public Safety Professional

As a former assistant in the Lake County State’s Attorney’s Office and the Attorney General’s Office, Mark brings an increased level of integrity and jurisprudence as Lake County Sheriff. Keeping Lake County Safe remains a top priority. Safety begins with a properly trained workforce and enhanced with educational programming available through schools, civic organizations as well as the Lake County Sheriff’s Citizen’s Police Academy, and Senior Advocate programs.

Proven Fiscal Manager

Operating under budget for seven years in a row, Sheriff Curran is a trusted steward of taxpayer dollars. Sheriff Curran initiated a cost-saving reorganization of the Court Security Unit. The unit formerly consisted of only full-time deputies. Today, 30 full-time Court Security Officers and 50 part-time Court Security Officers are members of the Court Security Unit, allowing the Office to re-allocate full-time deputies to patrol. The savings for a part-time employee, (including salary and elimination of benefits) is roughly $23,000 per deputy per year.
