Dennis R. Washington (born 1934) is an American billionaire industrialist who owns, or co-owns controlling interests in, a large consortium of privately held companies collectively known as the Washington Companies and, in Canada, another collection of companies known as the Seaspan Marine Corporation.

Early life[edit]

Born in Spokane, Dennis Washington grew up in Spokane, Bremerton, Washington, and Missoula, Montana.[2] His parents separated when he was very young, and Washington lived with his mother. He rarely saw his father, who worked in construction overseas. Washington did not grow up in a wealthy family. Additionally, he states his parents' divorce as his motivation to provide his own wife and children with a stable family environment.[3]


Following graduation from high school, he worked in construction in Alaska and Montana. He began his business career at age 30 in 1964, with a $30,000 loan and a single bulldozer[citation needed]. He created Washington Construction, which worked primarily on highway contracts and by 1969 was the largest contractor in Montana.[citation needed]

In the 1970s he moved into mining and dam construction. In 1986 he acquired a copper and molybdenum mine at Butte, Montana. He successfully reopened the mine and it became a very profitable operation. This success helped him diversify into railroads, marine services, coastal shipping, aviation and real estate. In 1996 Washington Construction acquired global construction and engineering company Morrison-Knudsen Corporation of Boise, Idaho, creating Washington Group International.[citation needed]

Included in the Washington Companies' holdings are:[citation needed]
