About Sal's Auto Service

A family-owned auto repair shop that has served Fullerton drivers since 2010, now under new ownership and still built on the same two words on our card: honest and thorough.

Under new ownership since February 2026

Owner Robert began his automotive career in 1982 and earned ASE certification in 1986. His hands-on experience covers wheel alignment, steering and suspension, brakes, electrical diagnostics, A/C systems, engine repair, drivability and general automotive service.

He also brings years of professional network engineering and technical troubleshooting. Modern vehicles are networks of computers, and that background means a methodical approach to problems that used to be solved by swapping parts.

The shop's history

Sal's Auto Service has served Fullerton since 2010. Its founder started in the trade in 1993 and ran M.D. Auto Service before opening this shop. The reputation customers describe in their reviews, honest answers and fair prices, is the one we intend to keep.
