Our History

Clausen and Sons is a third generation contractor established in 1960 in Malta, Montana by Pete Clausen.  Pete was running a Ford dealership and a Phillips 66 bulk fuel delivery and gas station/tire shop at the time, when he decided to get into the construction business.  He began selling and erecting Eaton grain bins.  In 1960, a Behlen representative named Chub Parks made a visit to Malta and convinced Pete to become a part of the Behlen family.  That year, the company became the second Behlen building dealer in Montana and has since built a highly successful business around Behlen building products.

In 1971, Pete sold the Ford dealership in Malta and moved his wife and five children to Zortman, Montana, a small mining community with a population of  27, counting the seven Clausens.  Having started working on buildings at an early age, Pete’s oldest son David was 17 years old at this point and took his senior year of high school via correspondence with Malta High School during 1972 – 1973.  Grain bins, Curvets and farm buildings were the primary focus of the business at that time.  Pete and his three sons traveled around the Zortman area, working under the name of “Clausen Wholesale.”  At this time, the business became a family affair.  Pete’s wife and two daughters would often travel with the family to job sites to do the cooking while the boys erected buildings.  The family enjoyed working together until the 1980’s, when David’s two brothers left Zortman and the business to pursue careers in the financial world.  By 1975, the family business took on a new name – “Pete Clausen and Sons.”

1979 was another milestone for Clausen and Sons, as a young man named Pat Newton had just graduated high school and began working for Pete. The company was incorporated in 1981, now bearing the name “Pete Clausen and Sons, Inc.”  Once Pete retired in 1993,  Dave continued running the business and opened a small office in Havre.  At that time, Pat Newton also joined Dave as a co-owner of “Clausen and Sons.” 

In 1996 Office Manager Paula Hanson and Project Superintendent Tracy McLain joined the team. After working many summers with her dad pouring concrete and doing other work on the job sites, Dave’s oldest daughter, Autumn, permanently joined the company in 2008 as a Project Manager. 

Throughout the years, Clausen and Sons has worked with numerous architects and engineers and managed, designed and built a variety of structures within various sectors of the economy.  One thing remains unchanged at Clausen and Sons and that is a commitment to safety, quality, integrity, craftsmanship, customer satisfaction and trust. This commitment is part of every project. From design to completion and subsequent maintenance, each phase of construction is completed with the utmost attention to detail and professionalism.
