Our Story

Liberty Mobile Mechanics was built from Carolina grit—founded by brothers Mark and Jonathan Kelterborn.

Mark, a mechanical savant, has been wrenching since he first gripped a socket at age six. From Audi to Zenos, he’s fixed, fabricated, and fine-tuned with precision and instinct. But it’s not just talent—it’s heart. Mark runs his own HVAC business with quiet excellence, solving problems others walk away from. He’s the kind of man who listens before he lifts a tool, who treats every job like it’s for family—because that’s how he lives. Intelligent, grounded, and endlessly capable.

Jonathan, a former robotics technician and automation systems supervisor turned entrepreneur, helped design and build advanced systems for companies like Tesla, BMW and Mercedes—before turning his focus toward something more personal, more lasting.

Together, we bring decades of experience, relentless problem-solving, and a shared vision: to build something that endures. Not just for ourselves—but for our families, our community, and the legacy we’re crafting every day.

We don’t just fix vehicles. We restore trust. We deliver truth. And we show up when it matters most.
