Since Louis Galliker founded the business in Johnstown in 1914, Galliker Dairy Company has remained rooted in its hometown and family dairy tradition. Today, family members are still involved in operations as more than 300 employees help distribute Galliker’s milk and ice cream across 10 states. The company is especially known in Pennsylvania for its Lightsafe Yellow Jug, introduced in 1992 to help protect milk’s nutrients from light.
