Western Star '1967–pr.

Western Star was founded in 1967. Originally headquartered in Cleveland, Ohio with manufacturing in British Columbia, it thrived by putting the driver-operator first and by delivering dependability and durability in the harshest environments. In 2002, Western Star production was moved to its new assembly plant in Portland, the headquarters of parent company DTNA. The Portland Manufacturing Plant began operations in 1969 and has built nearly 500,000 trucks since its opening.

Western Star sold its 100,000th truck in February 2006 after 39 years in business; it took only 14 years to sell the second 100,000 trucks.
