The old owner of Differentials Plus, David Ratledge, shaking hands with the new owner, Chris Giordano.

ABOUT

Differentials Plus has been the premier auto repair destination for residents of Hixson and its surrounding areas since 2012, when founder David Ratledge established the business on Middle Valley Rd. Leveraging extensive experience in automotive repair, particularly in the realm of differential maintenance, Ratledge addressed a critical need in the local community. However, it was his unwavering commitment to integrity and hard work that truly propelled the business forward, earning Differentials Plus a reputation for delivering quality repairs at transparent prices.

In 2022, the torch was passed to Chris Giordano, ushering in a new era while upholding the steadfast values and principles upon which Differentials Plus was built. Under Giordano's stewardship, our commitment to providing an exceptional customer experience remains unwavering, ensuring that every interaction is marked by professionalism, quality, and fairness.
