Sheriff's Mounted Posse


Organized in 1949, the Napa County Sheriff's Mounted Posse has historically distinguished itself with a half a century of service to the community and is the oldest working posse in the State of California.

This dedicated group of men and women assist the Sheriff's Offices throughout the County of Napa when the need arises for unique talents of horse and rider. Though the Posse's primary function is the performance of search and rescue, they are activated during local emergencies, such as floods, as an integral part of the public service team. Whether involved in the charitable or civic events, local parades, or lending a hand to deserving organizations, the Posse takes pride in their support of the community.

Donated Items

In addition to emergency and civic service, the Posse has donated medical and hospital equipment to different organizations for decades. Some examples of their spirit include presenting the first respirator for paramedic use in the Lake Berryessa area and car seats to local service groups for transportation of needy children to doctors. They also make available wheelchairs, walkers, and other accessories to the public at no charge.

Being a non-profit group, the Posse sponsors numerous fund-raising events throughout the year. These funds, and generous donations from area persons and businesses, not only support the operations of the Posse, but are passed on in order to sponsor youth athletics and agriculture, including Little League, 4-H, and the Future Farmers of America (FFA).

The Napa County Sheriff's Mounted Posse has maintained a tradition of excellence from the very beginning and strives to continue serving the community. It takes a special kind of person to dedicate themselves and the Posse is made up of just those kind of people.
