HENDERSONVILLE, N.C. — For nearly two decades, Matt Geouge was known locally as a diesel mechanic and business owner who loved trucks and built a successful shop around keeping them on the road.
Today, his story has become part of a national conversation.
In this exclusive interview with Hendo.Today, Geouge shares his journey from founding Spartan Diesel Technologies in Hendersonville at just 20 years old, to federal prosecution, prison, fatherhood, and ultimately receiving a presidential pardon.

From Small Business Owner to Federal Defendant
Geouge says his passion for diesel trucks began as a teenager after learning to work on a Ford Power Stroke engine.
In 2007, he launched Spartan Diesel Technologies in Hendersonville and built a reputation working on diesel pickups and commercial vehicles throughout Western North Carolina.
As emissions systems became increasingly complex on newer diesel vehicles, Geouge says customers began arriving with expensive and recurring repair problems involving diesel particulate filters, exhaust gas recirculation systems, and related emissions components. According to Geouge, many truck owners were frustrated by repair costs, downtime, and reliability issues affecting work trucks, farm vehicles, and commercial fleets.
What followed would eventually place Geouge in the center of one of the most controversial enforcement efforts involving diesel emissions modifications in the country.
Prison, Family, and a Son He Almost Missed Meeting
Perhaps the most emotional chapter of Geouge’s story has nothing to do with trucks.
Shortly before reporting to federal prison, Geouge and his fiancée learned they were expecting their first child.
He entered prison knowing there was a possibility he would miss the birth of his son entirely. During his incarceration he also experienced a serious medical emergency involving diabetic ketoacidosis that required hospitalization. He ultimately returned home before his son’s birth, but only after months of uncertainty and separation from his family.
Regardless of where people stand on the underlying legal issues, the human side of the story is difficult to ignore.
A Presidential Pardon
Earlier this month, President Donald Trump issued presidential pardons to multiple diesel mechanics and tuners who had been convicted under Clean Air Act prosecutions involving emissions modifications. Geouge was among those receiving clemency.
The decision marked a dramatic reversal in federal policy.
The Department of Justice announced earlier this year that similar cases would no longer be pursued criminally, although civil penalties may still apply in some circumstances.
Supporters argue these prosecutions unfairly targeted small business owners trying to solve reliability issues for customers. Critics argue emissions laws exist to protect public health and air quality and should continue to be enforced.
The debate remains active nationwide.
More Than Politics
One thing becomes clear while speaking with Geouge:
This story is bigger than politics.
It is a story about entrepreneurship.
It is a story about regulation and unintended consequences.
It is a story about family, resilience, and rebuilding after losing nearly everything.
Most of all, it is a story about a father, a business owner, and a man trying to move forward.
