John recalls when the local Deputy stopped by to talk and knew all of the neighborhood kids and their parents. As El Dorado County Sheriff, John has been bringing back those practices.

He went on to develop new programs and policies to streamline law enforcement bureaucracy and improve public safety. As a leader in law enforcement, John was appointed second in command for the newly formed Amador County Combined Narcotics Enforcement Unit (ACCNET) where he managed and oversaw daily unit operations.

His father served as a Pioneer Union School District Trustee where John, his brothers, and John’s 4 children and 5 nieces & nephews all attended and are still attending kindergarten through 8th grade. Following in his family’s footsteps of serving the community, John ran for and was elected to the Pioneer Union School District Board of Trustees in 2003 and reelected in 2007.  While on the Board, John fought hard to balance difficult budgets with a steady reduction in revenue and believes every child deserves a positive and safe learning environment.

They plan to see the next generations of their family continue to live in El Dorado County and have a vested interest in preserving the rural charm, quality of life and safety for families in our county.
