About High Rize Diesel LLC in Circleville, OH

At High Rize Diesel LLC in Circleville, OH, we believe in hard work, honest service, and doing right by every customer who walks through our doors. What started as a one-man operation in a garage during the pandemic has grown into a full-service, six-bay diesel dealership and repair shop right here in Circleville, OH.


Started in 2019 by Nathan Rizer, High Rize Diesel is the result of years of grit, experience, and dedication to diesel technology. We specialize in diesel pickups, vans, and fleets, offering expert service for Chevy, Ram, Jeep, Ford Transit, Sprinter, and more. 


Nathan’s story starts just outside of Circleville, where he graduated from high school in 2014. With a natural talent for hands-on work and a passion for engines, he applied to Ohio CAT, a Caterpillar dealership known for heavy equipment. Recognizing his potential, they sent him to Caterpillar College, where he spent two years studying diesel technology while interning at the dealership.


After graduation, Nathan spent eight years working full-time at Ohio CAT, gaining advanced technical knowledge and real-world experience with diesel systems. But during the COVID-19 pandemic, like many others, he had to rethink his path. He made the bold decision to go out on his own, starting with basic tools and big dreams in his home garage.


High Rize Diesel grew quickly. Within a year, Nathan expanded into a 60x80 shop. And by 2022, he took the next big step, opening a six-bay, full-service facility with the space, staff, and equipment needed to take on more work.
