Meet the Pros at Protrans Automotive in Riverside

Protrans Automotive, Riverside’s largest independent AAA-approved auto repair facility, is owned and operated by Michael and Samantha Radak. Michael and his father, Jack, started Protrans in May of 1992 after Jack retired from the space industry. A few years down the road, Jack was recruited back to Boeing, and Michael and Samantha decided to continue building the family business by adding general auto repair to transmission rebuilding. Today, we’re proud to offer Riverside drivers everything from auto diagnostics to brake repair to oil changes—alongside our transmission expertise—while maintaining the highest service standards in the auto repair industry.
