For Jeffrey King-Gardner, working at Chevron Richmond is not just a career, but a family tradition coming full circle.
A metals craft trainer at the refinery, King-Gardner’s trade roots go back to World War II, when his great-grandmother worked as a Rosie the Riveter in Oklahoma, welding around high explosives at an aircraft plant. His grandparents later met through the Boilermakers Union, passing down a family craft that reached his father and, eventually, him.
“When I got into the Boilermakers Union, I became a fourth-generation boilermaker in my family,” King-Gardner said.
Growing up, he recalled hearing family members discuss the trade around the dinner table. As he got older and had opportunities to experience the work himself, he said it felt like a “full circle” moment.
Born at Richmond’s former Brookside Hospital, King-Gardner moved to Vallejo at age six and grew up with his parents separated. After high school, a family friend helped him land an entry-level refinery job cleaning tanks and other equipment. After about three or four years, that hands-on experience led him to a four-year apprenticeship with Boilermakers Local 549 in Pittsburg.
Over the next seven or eight years working out of the union hall, King-Gardner honed his skills at power plants and refineries. In 2011, he also completed Chevron’s free local Regional Occupational Program (ROP) course, then led by longtime instructor Butter Sims. The program helped him learn about refinery career opportunities while preparing for resumes, interviews and the job application process.

While the work was rewarding, contracting through the union required travel, including out-of-state assignments. By 2016, King-Gardner wanted more stability. He and his wife had recently bought a home and were preparing for their first child when Chevron Richmond posted openings for experienced journeyman maintenance mechanics.
On Halloween that year, he started work at Chevron Richmond as part of the refinery’s first hiring group of experienced journeyman mechanics.
King-Gardner spent his first year working in Chevron Richmond’s operating areas as a mechanic before transferring to the boiler shop, where he put his specialty welding certifications to work for about six years. In September 2023, he became a metals craft trainer. Since then, he has helped hire, onboard and train 31 maintenance mechanics.
Safety is a major focus of that training, King-Gardner said.
“It takes three to four months of intensive training, safety qualifications, equipment instruction, and welding practice before someone ever steps foot inside an operating unit,” he said.

Now in his 20th year in the petrochemical industry, King-Gardner said one of the most rewarding parts of his role is passing along the knowledge and experience he has gained while helping prepare the next generation of workers. He has also participated in job fairs and recruitment efforts.
For people interested in entering the trades, King-Gardner recommends taking advantage of programs such as ROP, contacting local trade unions and companies, and developing welding fundamentals or earning certifications that can help candidates stand out in a competitive job market. He said opportunities remain plentiful for skilled boilermakers, pipefitters, welders and other tradespeople, with work available in refineries, power plants and other industries.
“If this is something you want to do, the opportunities are out there, but you have to apply yourself,” he said.
Today, King-Gardner lives in Oakley with his wife and two young sons, ages 10 and 6. Outside of work, he spends much of his time with his family, including attending sports activities and riding bikes. One of his sons has already developed an interest in hands-on work and sometimes asks his father to show him how to use tools around the house.
Between training new mechanics at the refinery and sharing his knowledge with his sons at home, King-Gardner is continuing a trade tradition in his family that dates back to the World War II era.
