Dairy Maid Dairy makes fresh Maryland milk and other dairy products from milk supplied by local farms in Frederick. Its family-run processing facility stands on the same grounds as the Excelsior Dairy, founded in 1894; Joseph Vona purchased the plant in 1946 after returning from World War II. The company says its milk is antibiotic-free and made under a pledge against artificial growth hormones.
