William Guerin, George Wondriska, and Sam Casanas founded Master Cast in 1969. The original foundry was located along the Fox River in Batavia, Illinois. As business and the need for space grew, the company bought the former Lingren Foundry building in Batavia. Guerin bought out Wondriska and Casanas in the 1970’s and today the company is run by his sons Brian and Tim.
