The Operations Division has principal law enforcement jurisdiction in all unincorporated areas of Stanislaus County. The Sheriff provides law enforcement services to a population of over 200,000 covering an area of approximately 1,521 square miles.  The Sheriff also provides the full spectrum of law enforcement services to four Contract Cities, which are Patterson, Riverbank, Hughson and Waterford.

The Division is divided into two units:

Patrol

Investigations

In Patrol, uniformed Deputy Sheriff's respond to citizen calls for assistance on a 24-hour, 7 day-a-week basis. Deputy Sheriff's investigate crime, make arrests, provide preventive patrol, and render assistance or aid where necessary and are tasked with protecting life and property.

The Investigations Division is responsible for the follow-up of major crimes that are reported to the Department. Detectives routinely recover stolen property, identify and apprehend offenders, collect preserve and prepare evidence, and testify at trial.

As a Sergeant, his most memorable assignment was supervising the homicide team in the Crimes Against Persons unit. Later, he worked at Riverbank Police Services as a patrol supervisor until his promotion to Lieutenant in 2005. As a manager, one of Tim's assignments included working with the S.W.A.T., team as a tactical commander on S.W.A.T., operations.
