ABOUT ROHNERT PARK TRANSMISSION
Family-Owned Excellence in Auto Repair Since 1997
Our Story: Three Decades of Trust
Founded in 1997, Rohnert Park Transmission & Auto Repair has been a cornerstone of automotive excellence in Sonoma County for over 25 years. What started as a small family-owned transmission shop has grown into one of the most trusted full-service auto repair facilities in Northern California, while never losing sight of the personal touch and commitment to quality that built our reputation.
Our journey began when our founder, a master technician with over 15 years of experience at the time, recognized the need for honest, reliable auto repair services in Rohnert Park. Having worked for various dealerships and independent shops, he understood that customers deserved better – transparent pricing, genuine care, and technical expertise that actually solved problems rather than creating new ones.
The early years were challenging but rewarding. Starting with just two bays and a handful of loyal customers, we focused on what mattered most: delivering exceptional transmission repairs and building trust one customer at a time. Word of mouth spread quickly in our tight-knit community, and soon we were known as the go-to shop for complex transmission problems that other shops couldn't solve.
As demand grew, so did our capabilities. By 2005, we expanded our services to include complete auto repair, from routine maintenance to complex engine work. We invested in state-of-the-art diagnostic equipment, continued education for our technicians, and additional service bays to reduce wait times while maintaining our high standards of quality.
Today, Rohnert Park Transmission operates from a modern 8-bay facility equipped with the latest technology and staffed by a team of ASE and ATRA certified technicians. Despite our growth, we remain a family-owned business committed to treating every customer like a neighbor and every vehicle as if it were our own. Our children have grown up in the shop, learning the values of hard work, integrity, and service to others that define our business philosophy.
