Eric Twing
Eric's passion for automotive work began at a young age, turning wrenches alongside his grandfather in the family garage. It quickly became clear that he had a natural mechanical ability, which he chose to pursue as a career. In the mid-1990s, Eric attended technical college to hone his skills and deepen his knowledge of automotive systems. After graduation, he gained valuable hands-on experience working at several local dealerships and independent repair shops.
Over the years, he earned his ASE certifications and has continued to grow in the field, building a reputation for quality workmanship and trusted service.
​
Eventually, Eric joined the team at Master Mechanics Automotive, where his role has grown beyond repairs and diagnostics. Today, he helps Greg run the shop, bringing leadership, technical expertise, and a strong work ethic to the business. Together, they’ve built a solid partnership focused on delivering reliable service and creating a trustworthy environment for their customers.
