San Mateo County has released the names of the candidates qualified to serve as the next sheriff after the San Mateo County Board of Supervisors removed former Sheriff Christina Corpus from office.
The chosen candidate will serve until 2028 due to a state law that changed the date of the sheriff’s election. While the board of supervisors was originally considering having the new sheriff chosen in a special or general election, the board narrowly voted to appoint a sheriff instead.
Some members of the board were concerned that an elected sheriff would choose to cooperate with Immigration and Customs Enforcement and that appointing a sheriff would help the department heal.
Six candidates, each with decades of local law enforcement experience, have applied for the position. State law requires a sheriff to live in the county and have credentials from the California Commission on Peace Officer Standards and Training.
Corpus was the county’s first female and first Latina sheriff. None of the candidates are female or identified as Latino in their applications.
The candidates will go before the Board of Supervisors on Thursday at 1 p.m. in the Board Chambers, where they will be interviewed publicly. The board will then select a group of finalists, although an exact number of finalists has not been set.
The finalists will then participate in an open candidate forum on Monday, Nov. 10, where members of the public can submit questions to be asked.
On Wednesday, Nov. 12, the board will conduct final interviews in a public meeting and make a selection of the next sheriff.
The candidates are Gilroy Interim Police Chief Kenneth Binder, City Manager of Hillsborough John Doug Davis, former Assistant Chief of the San Francisco Police Department David Lazar, Solano Community College District Police Chief Brian Wynn Huynh Travis, Sgt. David Weidner of the San Mateo County Sheriff’s Office, and former SFPD Capt. Robert Yick.Â
Here are each of their qualifications, according to their applications and resumes:
Gilroy Interim Police Chief Kenneth Binder

Binder began his 27-year law enforcement career in the Santa Clara County Sheriff’s Office, working his way up to become undersheriff in 2020.
He briefly served as Acting Sheriff of Santa Clara County in 2022 after former Sheriff Laurie Smith retired early, just before a civil grand jury convicted her of corruption and willful misconduct. Binder said in his application that in his role as acting sheriff, he helped stabilize the Sheriff’s Office.
Binder also served as police chief for three cities that contract with the Santa Clara County Sheriff’s Office, where he focused on employing “21st century policing,” which is a modern policing approach that prioritizes community engagement and officer wellness.
Binder retired from the Sheriff’s Office in 2024 before taking up the position of Gilroy Interim Police Chief in June this year. He moved to San Mateo County on Nov. 1, 2025.
Hillsborough City Manager John Doug Davis

Davis currently serves as the city manager of Hillsborough after a 34-year career in Hillsborough Police Department. He served as the Police Chief of HPD from 2018 to 2023. He is also currently the chief administrative officer of the Central County Fire Department where he oversees fire department services for Hillsborough, Burlingame, and Millbrae.
Through these roles, he has managed large budgets and has worked collaboratively with labor unions, according to his application.
Davis also has “long-standing” ties to the San Mateo County Sheriff’s Office, where he was a member if its SWAT team. He also served three years as the commander for the Sheriff’s Office Gang Intelligence Unit and Gang Task Force, according to his resume. He has lived in San Mateo County for 36 years.
Retired SFPD Assistant Chief David Lazar

Lazar recently ended a 33-year run with the San Francisco Police Department, where he rose through the ranks to become assistant chief for three years under former Police Chief Bill Scott.
As assistant chief, he oversaw 1,700 sworn and non-sworn staff.
He also has experience in promoting police reform and community policing. He established SFPD’s Community Engagement Division with the goals of boosting community policing, reducing bias within the department, and evaluating use-of-force policies.
If appointed, his priorities would be trying to heal the Sheriff’s Office through demonstrating strong leadership and bringing back honesty, professionalism, and transparency, he said. He would also encourage deputies to have a voice and allow them to contribute to the day-to-day operations. Lazer moved to San Mateo County on Nov. 1 but has longstanding ties to the area as he went to school at College of San Mateo and his mother lives in the county.
SFPD Capt. Kevin Lee
Editor’s Note: Lee withdrew his name from consideration on Nov. 6, the day after the candidates were announced.

Lee has been the captain of SFPD’s Richmond Station since July and has more than 26 years of law enforcement experience in San Francisco. He began his career as a deputy in 1999 at the San Francisco Sheriff’s Office, where he worked in corrections and court security.
He then transitioned to become an officer with SFPD, serving as a sergeant, lieutenant, and now captain. He is bilingual, fluent in Cantonese.
As captain of SFPD’s Richmond Station, Lee oversees a multi-million-dollar budget, 75 sworn and civilian personnel, and he directs all aspects of field operations.
If appointed sheriff, he would focus on implementing 21st-century policing values, including strengthening community trust and promoting officer wellness, he said. He would also expand advanced technology to aid in policing, including the use of drones. He has lived in San Mateo County for over 20 years.
Solano College District Police Chief Brian Wynn Huynh Travis

Travis has more than 25 years of public safety experience and currently serves as police chief for the Solano Community College District. He helped establish the district’s first POST-accredited police department from the ground up, according to his resume. POST, or the California Commission on Peace Officer Standards and Training, sets standards for law enforcement training programs and certification.
Originally from Vietnam, Travis relocated to San Mateo as a young child with his siblings. He served in the U.S. Army before becoming a police officer in the South San Francisco Police Department.
Travis worked for 14 years in the Solano County Sheriff’s Office and rose to the rank of lieutenant, where he gained experience in budgeting, supervising and overseeing sworn staff.
He also has experience in directing Solano County’s emergency response efforts as a commander for the county’s Regional Mutual Aid Response Mobile Field Force Team and also as a manager for the county’s Office of Emergency Services. Travis moved to San Mateo County in 2025 but was raised in the county.
SMC Sgt. David Weidner

Weidner is the only candidate from within the San Mateo County Sheriff’s Office. He has served in the Sheriff’s Office for 25 years, eventually advancing to his current position as sergeant.
In the Sheriff’s Office, he has held roles in corrections, patrol, field training for new deputies, and firearm instruction.
As sergeant, he oversees patrol and jail operations to ensure that deputies are complying with policy and use of force practices.
He is also the range master and lead training coordinator, where he trains hundreds of deputies in handling firearms. Additionally, he manages the nearly $1 million annual range and training budget.
His three priorities as sheriff would be rebuilding morale within the Sheriff’s Office, improving training standards for deputies and investigating recent in-custody deaths in the jails, and boosting transparency, he said. Weidner has lived in the county for 53 years.
SFSU police Capt. Robert Yick

Yick is a captain and second-in-command for the San Francisco State University Police Department, where he oversees daily operations, patrol staff, budget management, and manages public safety for large university events.
For 29 years, Yick served in the SFPD. He held captain positions at the Central and Taraval stations, as well as serving as acting commander of the Metro Division, where he supervised three stations.
During his time at SFPD, he has helped promote community engagement programs, streamlined the officer hiring process, and implemented technology to boost efficiency, he said.
His priorities for the role of sheriff include ensuring that officers do not work with federal immigration authorities, holding himself and staff accountable, and boosting department morale through focusing on increasing staffing and prioritizing officer wellness, according to his application. Yick moved to the county on Nov. 1, 2025.
