Built on Trust, Strengthened by Community, and Guided by a Clear Vision
At Wrench Auto Service, our story is rooted in honest work, long-term relationships, and a deep respect for the people we serve in Middleton, WI and the surrounding communities. For years, drivers have trusted Wrench Auto as the place to bring their vehicles when they wanted straight answers, skilled repairs, and service that felt personal rather than transactional.
In 2025, Wrench Auto Service entered an exciting new chapter under the ownership of Bert, a local professional with a clear vision for the future of the shop. While ownership has evolved, the foundation remains the same: quality repairs, transparent communication, and a commitment to doing right by every customer who walks through the door.
The Early Years of Wrench Auto Service
Wrench Auto Service was built as a local, independent auto repair shop with a simple mission, take care of people by taking care of their vehicles. From routine maintenance to complex diagnostics, the shop earned its reputation one repair at a time.
Customers returned not just because their cars were fixed properly, but because they felt heard and respected. Over time, Wrench Auto became known as the shop neighbors recommended to neighbors, a place where trust mattered just as much as technical skill.
That reputation is something we protect fiercely to this day.
A New Chapter Begins in 2025
In 2025, Bert purchased Wrench Auto Service with a strong belief that a great auto repair shop should never lose its human side. His goal was not to reinvent what worked, but to strengthen it.
Bert brings a deep appreciation for automotive craftsmanship and a customer-first mindset. He understands that every driver’s situation is different. Some want to keep their vehicle running reliably until it reaches 250,000 miles. Others simply need safe transportation for the next season of life. Under his leadership, the shop focuses on helping customers make informed decisions that align with their goals, not pressure-based recommendations.
Since taking ownership, Bert has invested in improved systems, modern diagnostic tools, and continued technician training, while preserving the approachable, neighborly atmosphere that Wrench Auto is known for.
