DeRuosi Nut is a walnut processing facility located in California's central valley. Our facility processes both inshell and shelled walnuts and offers a vast variety of walnuts including Chandler, Hartley, Vina, and Howard.
In 1947, after serving our country in WWII, Michael DeRuosi Sr. purchased an existing fruit dehydrator in Escalon, CA. Over the next several decades the plant processed raisins, apricots, prunes, and walnuts. In 1980, at the age of 12, Michael DeRuosi III started helping his grandfather run the prune plant.
In 1994, after graduating with a business degree and working for a few years in the banking industry, Michael DeRuosi III moved back home to partner with his grandfather and form DeRuosi Nut. Since inception, the company has expanded slowly and conservatively into a business that is now one of the premier walnut processors in the state of California.
