About Us
Jumbo Brand Sunflower Seeds are owned by Klein Bros. Holdings, Ltd. We’re a privately held California corporation based in Stockton, Ca. The Klein family has been growing crops in the San Joaquin Valley for four generations.
Going Green:
Over the last several years we’ve made many energy saving improvements including the conversion of all the interior lighting to high efficiency T8 fluorescent lamp fixtures. In an effort to further reduce our carbon footprint, we eliminated our propane forklifts and replaced them with battery powered forklifts. We also recycle used cardboard, plastics, office paper and any other materials that can be kept out of the landfill.
