OSI Group is a US-based food and meat processing firm that serves the foodservice and retail industries. Its headquarters is located in Aurora, Illinois. OSI Group started in Oak Park, Illinois in 1909 as a family meat market. In 1917, it expanded into a wholesale meat franchise and relocated to nearby Maywood, a Chicago suburb. Over time, Otto & Sons built itself an excellent reputation for offering quality meat.
Upon opening its first store in Illinois in 1995, McDonald’s chose Otto & Sons as its exclusive supplier of fresh ground beef patties. The founder and CEO of McDonald’s, Ray Krock, formalized the deal through a handshake with Otto Kolschowsky heirs. Kroc and Otto Kolschowsky’s sons forged a healthy personal relationship for quite a long time. Soon, supplying beef to local McDonald’s food chains became Otto & Son’s core business. In 1973, Otto & Sons launched a new meat processing plant with liquid nitrogen freezing tunnels in West Chicago. Accordingly, it began a separate unit that would serve non-McDonald’s businesses.
Upon changing its name to OSI Group in 1975, Otto & Sons became an exclusive supplier of fresh ground beef patties to the McDonald’s. Over time, it grew in size and succeeded as McDonald’s scaled globally. In 1999, OSI Group entered into a contract with Best Chicago Meat to use the Glenmark brand. Nonetheless, Best Chicago Meat wholly acquired the Glenmark brand in 2011. As of 2016, OSI Grouped ranked 58th as one of the leading private meat processing companies in the world, at $6.1 billion.
