John Mason: Mechanic Turned Business Owner

From a young age, John had a passion for the auto industry. In high school, he worked at a gas station where he received training to become a mechanic. Eager to gain more knowledge, John studied auto repair and technology during his college career. Following his graduation, he worked at numerous auto repair shops. With his experience as a mechanic and industry insight, John felt confident in his ability to start his own business. In 2000, he did just that. For two decades, Northside Auto has been a reliable auto shop for those in need, and John hopes his enterprise will continue to grow by leaps and bounds.
