Orville Kelvin “Bum” Post opened the feed store in Tucson in 1936. At that time, Fort Lowell was a dirt road and the surrounding area was farm and ranch land settled by the Binghamton Community of Mormons. Though the Post Family has not owned the store since 1973, OK Feed & Supply has remained a locally and family-owned business that continues to evolve to meet the needs of its customers. As rural living in the area decreased, OK Feed began stocking holistic and high-quality feed, not only for livestock but for pets as well. At that time, most people were content to feed grocery store brands with low-quality ingredients. OK Feed set itself apart by providing premium, independent, holistic brands not available elsewhere and nutritional training to its employees. This gave birth to a passion to provide customers with exceptional nutrition and advice.
