Our History

Mark’s Motors has proudly served the Port Saint Lucie community since 2016. Founded by Mark Greisen, the shop was built from the ground up with a simple mission: provide honest, reliable automotive service that customers can truly trust. Through hard work, integrity, and a commitment to quality repairs, Mark established a reputation for dependable service and straightforward communication — values that continue to define the business today.

Over the years, Mark’s Motors became known not just for skilled workmanship, but for treating customers like neighbors. Fleet managers, families, and local businesses alike came to rely on the shop for consistent, high-quality service delivered with transparency and care. That strong community reputation is something we are proud to carry forward.

In 2026, Mark Greisen sold Mark’s Motors to Complete Fleet Repair and Matt Harper, ensuring the business would continue to grow while staying true to the principles it was founded on. This transition represents not an ending, but a continuation — combining Mark’s trusted legacy with Complete Fleet Repair’s expanded capabilities and long-term vision for serving Port Saint Lucie and the surrounding areas.

Mark isn’t going far. He will remain involved part-time during the transition, continuing to lend his expertise and experience while enjoying more well-earned time with his grandkids and spending more days camping and outdoors. His foundation, reputation, and relationships remain at the heart of what we do.

At Complete Fleet Repair dba Mark’s Motors, we are committed to honoring the past while building the future — delivering the same trusted service the community has relied on since 2016, with the added strength and resources to serve you even better.
