Branch served: U.S. Navy, AS1 (AW/SW), 7 years of service
Joshua Seley never imagined he would spend so much of his life in a classroom. Growing up in Lake Park, MN, he was more interested in sports and working with his hands than academics. But a conversation with his grandfather, a Navy veteran, convinced him that military service could provide the technical training and direction he needed.
At 18, Seley enlisted in the U.S. Navy. Over the next seven years, he completed two deployments aboard the nuclear-powered USS John C. Stennis, maintained equipment essential to aircraft carrier operations, and eventually became an instructor responsible for training other sailors.
That experience laid the foundation for an entirely different mission.
In 2019, while pursuing his MBA at North Dakota State University, Seley founded Deckplate Diesel, a Fargo-based semi-truck repair business. What began as a one-person operation has grown into a company with eight full-time employees, providing in-shop repairs, fleet maintenance, and around-the-clock mobile service.
Today, Seley is also a second-year law student at the University of North Dakota. He plans to practice business law in North Dakota after graduation and is currently enrolled in the UND Business & Non-Profit Law Clinic. Although his management team handles much of the shop’s daily operations, he remains deeply involved in the business, and is still the person most likely to answer a call in the middle of the night.
We asked Seley how his military experience shaped his approach to business, what he has learned about leadership, and why serving others remains central to his work.
What did you do during your time in the Navy?
I served on active duty in the U.S. Navy from June 2008 to June 2015 as an aviation support equipment technician. That’s a fancy title for a diesel technician who fixes equipment like tow tractors used on the flight deck of an aircraft carrier.
I was stationed aboard the USS John C. Stennis (CVN 74), a nuclear-powered aircraft carrier, where I completed two deployments. Later, I was stationed at Naval Air Station North Island in California as an instructor, teaching new recruits how to maintain and repair equipment.
It was an incredible experience that prepared me for much more than working on diesel engines.
