The Great Northern Story

Reliable & Value-Driven

As young boys running around the foothills of the Bridger Mountains, Jesse and Rainor Kjelsrud enjoyed hunting, fishing, and hiking. They were taught to treat people as you want to be treated, and always have integrity.

As adults, they have a combined 15 years experience in the steel and aluminum industry and saw a need for a high-quality steel roofing and siding manufacturer in the Gallatin Valley that truly cared about the customers needs. They decided to reach out to longtime friend Jason Kostelecky for guidance and a partnership. Jason has over 30 years experience in the construction industry. The 3 of them together formed Great Northern Metal Company in November 2019. In March 2020, they brought on Thain Cook as co-owner.
