MARKETON INC., headquartered in El Monte, California, was founded by Constantino Miguel, who moved from his birthplace, Asturias, Spain, to Havana, Cuba in 1958, to work as a salesman with his uncle. Shortly after the Castro revolution, he moved back to Spain, before heading to America in 1968. By 1972, he opened his first neighborhood market in Pasadena, California, before opening a number of more stores over next several years.

Today, Marketon operates 5 full line supermarkets in the neighboring state of Nevada, with 4 stores in Las Vegas, 1 store in Reno and recently re-branded its stores to its new name, Marketon.
