He had his first job soon after graduating high school doing general maintenance on vehicles, while simultaneously attending automotive trade school.

Carlos is ASE Master Certified with advanced diagnostics and hybrid endorsement. He is a licensed smog technician. Carlos enjoys working on all makes of vehicles, and sees it as a challenge—like solving a puzzle (some makes/models give you more clues than others!). Time commitments outside of work go to family, church, and the home. When he has time, Carlos competes in gun competitions with friends, and he also likes to hike to stay in shape.

Kevin gets a kick out of working on police cars, too. He prides himself on clean, presentable work—customers may not always understand what was done to their cars, but everyone knows clean! Kevin enjoys working at ACE because he’s worked with the same core technicians for many years and they are all pretty close. Kevin is a Bay Area native, and lives in Clayton. He loves Northern California! Most of his free time is spent with friends, his folks, or his dog. He enjoys hiking in the San Ramon/Alamo hills and is always up for an exploratory hike!
