The beginnings of Diaz Foods can be traced back to 1969, when Domingo Diaz and Julio Rene Diaz, a father and son team, opened their first grocery store called Diaz Market in Midtown Atlanta. When their business quickly grew to five stores, Domingo and Julio recognized the need for a distribution center, thus Diaz Foods was formed in 1980.

As the Hispanic community in the United States has grown, so to has Diaz Foods. With over 500 employees, and consistent annual growth of 20-30%. The Company maintains approximately a quarter of a million square feet of office and warehousing space to support its extensive distribution network, including Diaz Foods' newly remodeled warehouse and office space on thirteen acres on Fulton Industrial Blvd, Diaz Produce's space at the State Farmer's Market in Forest Park and Tortilla's de Casa, a tortilla manufacturing plant off Fulton Industrial Blvd.
