Valley Dairy Restaurants operates a Pennsylvania restaurant chain and makes its own premium ice cream, a tradition that began with the first Valley Dairy Restaurant in 1938. Its ice-cream heritage goes back to Joseph A. Greubel, who began commercial production in Derry in 1884; Fairview Dairy in Windber, purchased in 1946, remains the home of Valley Dairy ice cream. The company says its ice cream is made with fresh ingredients and is sold through its restaurants and select distributors.
