Tulare County Undersheriff Dahl Cleek, Captain Jim Hinesly, Lieutenant Gary Chambers and Lieutenant Ramon Alanis all retired.
The men have 142 years of service between them.
The special celebration was held at the Tulare County Sheriff's Headquarters to honor the men for their career contributions.
"38 years it's time to allow new leadership to develop styles, more positive thinking opportunities, and take the department to a place that can maybe can go further without us," Cleek said.
Some of the retirees will be taking some time to travel while others want to continue serving the public in some form.
