WESTMINSTER, CA -- In another indication of his extensive, wide-ranging support among working men and women in the race for the Orange County Board of Supervisors First District, today Westminster Councilmember Sergio Contreras announced endorsements from three prominent labor unions: Southwest Regional Council of Carpenters, International Brotherhood of Electrical Workers (IBEW) Local 441, and UA Local 582 Plumbers & Steamfitters.

Southwest Regional Carpenters Local 714 representative Rich Gomez released the following statement announcing their endorsement:

“Sergio Contreras is the Southwest Regional Council of Carpenters’ choice for Orange County Supervisor. As a City Councilman and former school board member, he understands the needs of his constituents and how to get things done for people. He understands the needs of business and their workers and the importance of skilled training opportunities for our young people and safe working environments for all.  We are excited to see the improvements Sergio will make on the Board of Supervisors to ensure that Orange County will  have a skilled and trained workforce that will provide good wages and attract businesses to Orange County.”

The leadership of UA Plumbers & Steamfitters Local 582 also released the following statement:

“The United Association of Plumbers, Steamfitters, Welders, & Apprentices of Local 582 here in Orange County would like to formally announce our endorsement of our labor candidate in District 1 for the Orange County Supervisors, Sergio Contreras.  Sergio has shown candid leadership in the city of Westminster as a council member and former school board member.  He undoubtedly will continue to keep us, blue-collar workers, at the forefront of all decisions made stemming from the Board of Supervisors.  Today, organized labor is not a priority for our current supervisors.

The first Supervisorial District includes the cities of Garden Grove, Santa Ana, Westminster, the unincorporated community of Midway City, and parts of Fountain Valley. The first Supervisorial District is 42% Democratic and 24% Republican by registration – making it one of the most flippable major local offices in California.

Sergio Contreras, a husband, father, homeowner, and registered Democrat, has served on the Westminster City Council since 2012, where he successfully championed the largest upgrade to Westminster’s park system since 1996, encompassing 22 park facilities and representing a $10.4 million investment in the community. Contreras oversaw the city’s first general plan update in decades. He also placed emergency call boxes in all Westminster parks to enhance public safety, and fought to place outdoor exercise equipment in local parks to improve public health.

Contreras previously served on the Westminster School Board from 2004 to 2012, including serving as president of the board in 2012. On the School Board, Contreras helped pass a $130 million school bond to modernize Westminster’s school facilities and make them safer. In that role, he established an all-day kindergarten system, making Westminster School District the first in Orange County to provide day-long kindergarten at all school sites. Contreras also increased access to music and arts programs districtwide, while expanding after-school programs.

Now, Contreras works as the Senior Director of Education and Healthy Schools for the Orange County United Way where he creates strategic community partnerships to empower students from disadvantaged socio-economic backgrounds.  Contreras lives in Westminster with his wife Adriana, where their children Sergio III and Chloe attend local schools.

Recently, Contreras's upbringing and life's story was featured in the OC Weekly, which you can find here.
