It is an honor to represent the residents of Alameda County’s Fourth Supervisorial District. This diverse district includes portions of Oakland, from Montclair in the north to Oracle Arena and coliseum in the south, and the communities of Ashland, Castro Valley, Cherryland, El Portal Ridge, Fairmount Terrace, Fairview, Hillcrest Knolls and Pleasanton. As your supervisor my office has worked to engage the communities of District Four to build strong livable communities. Over the years we have worked hard together to protect open space, strengthen our healthcare system, and create walkable and safe neighborhoods. Please use this site to interact with me. Delivering service is important to me and I will continue to be accessible and collaborate with you. Thank you for visiting.
