CenterOak Partners LLC , a Dallas-based private equity firm, recently announced it has completed a majority recapitalization of Grismer Tire & Auto Service, a leading operator of tire and automotive service centers.

Terms of the transaction were not disclosed.

Headquartered in Dayton, Ohio, Grismer operates 28 locations across the Dayton, Columbus, and Cincinnati metropolitan areas. Founded more than 90 years ago, the company has built a strong regional brand based on high-quality service, trusted customer relationships, and competitive pricing. Grismer provides a full suite of mechanical repair and preventative maintenance services.

“The automotive service sector continues to benefit from strong tailwinds, including an aging vehicle fleet and increasing repair and maintenance complexity,” said Jason Sutherland, managing partner of CenterOak. “Grismer aligns with our focus on investing in essential, non-discretionary service businesses supported by recurring customer demand. This investment represents our fourth automotive service platform, and we look forward to applying our experience to support Grismer’s continued growth.”

“We are proud of what Grismer has accomplished as a second-generation, family-owned business over its more than 90-year history and believe CenterOak is the right partner to build on our legacy,” said former majority owner John Marshall. “Their sector experience, along with the integrity and thoughtfulness they demonstrated throughout our discussions, gives us great confidence in their ability to guide the Company through its next stage and deliver exceptional service to customers.”

CenterOak brings significant experience in the automotive service sector, having previously invested in CollisionRight, FullSpeed Automotive, and TruRoad.
