Originally based in Killdeer, North Dakota, the company was founded by Virgil and Juanita Jensen in 1929 as a crushing company. In 1950, the business relocated to Mobridge, South Dakota, and was renamed to what is now known as Jensen Rock and Sand, Inc. Over the next thirty years, Virgil, Juanita and their two sons (David and Derry) continued the expansion of the business by including chip-sealing, redi-mix, and asphalt paving services into their product offering.
In 1980, Juanita retired and two years later Derry sold his portion of the business to his brother David who then continued the operations with his two sons Kenny and Kyle, and his wife Valynn.
