Clark Bros. Inc. is a heavy civil contractor based in the Central San Joaquin Valley. Founded by Norman Clark and his two bro ... thers in the late 1930’s, the original Clark Brothers company was established in Dos Palos, California more than 70 years ago and spans three generations of Clark Brothers in construction and farming. In the early years, the land leveling company grew to include farming and crop dusting. After Norman’s premature death in a plane crash in 1949, his two teenage sons, Allan and Norman, Jr., continued the business of dirt moving and farming, developing large farming operations in Arizona and California and construction projects of highways, dams and agricultural related heavy civil construction. Today under the third generation of Clark Brothers, the company has expanded into all forms of construction, including structural concrete, earthwork, paving, mechanical piping, sewer plants, water treatment plants, and renewable energy projects. read more
