Metropolitan Stevedore Co., established in 1923 in Southern California and with business roots dating back to the 1850s gold rush era through its original San Francisco parent corporation, California Stevedore and Ballast Co., is celebrating its 90th anniversary. Through the years, Metropolitan Stevedore Co. became known as Metro, so in 2008 the decision was made to use Metro Ports as the new brand for the various key operating companies of Wilmington, Calif.-based Nautilus International Holding Corp.
