About Us
Welcome to Harmon Truck Service, your premier destination for unparalleled truck servicing in Sullivan, MO, at 1411 South Service Road West. Since our inception in 2015, we have been committed to excellence, innovation, and customer satisfaction, carving out a niche in the truck service industry.
Harmon Truck Service,
Initially known as Clarke Power Service, was rebranded and invigorated under the visionary leadership of Jason Harmon. A seasoned technician trained in the nuances of truck service, Jason took over the reins after the business encountered financial hurdles. His deep-rooted passion and expertise, honed over years of working on various projects, laid the foundation for what Harmon Truck Service is today.
Our humble beginnings saw Jason operating out of a service truck, tackling jobs that were often overlooked. This relentless drive and commitment to service excellence saw us rapidly grow. Today, our state-of-the-art facility boasts 12 service bays and a team of five highly skilled technicians, ensuring that your truck servicing needs are met with the utmost efficiency and expertise.
