Stater Bros. is rooted in the American tradition and proudly celebrates a rich legacy of service to this great nation. Tracing its beginnings back to a small grocery store in Yucaipa, CA, twin brothers and World War II veterans Cleo and Leo Stater purchased the original Stater Bros. Market from W.A. Davis with a $600 down payment.  In the midst of the Great Depression, Stater Bros. officially opened for business on August 17, 1936.
