At Great Northern Truck and Auto LLC, I bring 17 years of hands-on experience as a diesel technician, specializing in the diagnosis, maintenance, and repair of heavy-duty trucks. Over the years, I've built my reputation on honest work, dependable service, and quality repairs that keep vehicles on the road. While my primary focus is heavy trucks, I also provide reliable repair and maintenance services for passenger cars and light duty trucks. Whether it's routine maintenance or complex repairs, my goal is to deliver trustworthy workmanship and exceptional customer service on every job.
