Although its roots can be traced all the way back to the days of William the Conqueror, the Office of the Sheriff was established in the United States in the 1630s, courtesy of English colonists who settled in Virginia.
When New Mexico became a U.S. territory in 1861, the northwest portion of the state was designated as San Juan County. In 1862, the county became part of Rio Arriba County and it wasn’t until 1887 that San Juan County was recognized once again as a county. Since its existence the San Juan County Sheriff’s Office has steadfastly remained committed to serving the residents of San Juan County.
The Sheriff is a constitutional office with the Sheriff being elected to serve a four year term.
