Seaside Diesel Repair, LLC

Founded in 2007 by Travis Koski in a small rented shop, Seaside Diesel Repair, LLC quickly earned a reputation across Southeast Alaska for uncompromised quality of work and innovative mechanical problem-solving. By 2013, that dedication drove our expansion into a permanent facility in Lemon Creek, where we proudly became the authorized Cummins Dealer for Northern Southeast Alaska, as well as the region’s trusted provider for Isuzu and International warranty service.

In 2026, the company entered an exciting new chapter of local ownership. Scott Haas, who successfully steered the shop’s daily success as our Operations Manager for nine years, purchased the business. Having been at the heart of our operations for nearly a decade, Scott’s ownership ensures a seamless continuation of the elite craftsmanship and customer service our clients trust, while expanding our vision to meet the full, modern demands of our commercial partners.

Today, Seaside Diesel Repair has evolved into a truly complete service center. We specialize in the maintenance and repair of medium to heavy-duty diesel and gas vehicles, but we don’t stop at the bumper. We maintain and repair practically everything your business uses to operate. From over-the-road transport, Thermo King/Carrier reefer units, and structural box truck repairs, to warehouse equipment—including forklifts and electric floor jacks—if your business drives it, lifts with it, or hauls with it, we fix it.

Beyond our shop doors, we are also a leading provider of over-the-counter parts sales throughout Southeast Alaska. We stock a wide selection of parts for all areas of truck, trailer, and equipment repair, making it fast and easy for local fleets and independent operators to get the components they need right when they need them. Backed by this massive parts inventory and factory-certified technicians utilizing up-to-date diagnostic technology, Seaside Diesel Repair remains Southeast Alaska’s premier, all-in-one fleet and equipment authority.
