Fresh and family-owned, Keystone Food Service has been Oklahoma’s premier food management company since 1993. Our philosophy is simple: we provide food our customers love at a price they can afford. We do this by buying fresh foods in bulk and refusing to cut corners in our preparation. We bake our own chicken, and roll our own enchiladas, ensuring maximum taste and freshness. We don’t thaw and reheat. We cook, and our customers love the Keystone difference.

Keystone is revolutionizing the food service industry one school at a time.
