Leprino Foods’ history dates back over 70 years, when Jim Leprino first started making small batches of mozzarella for local markets and eateries in the Little Italy neighborhood of Denver. We’ve grown a bit since then. Today, Leprino Foods is the world’s largest manufacturer of mozzarella and lactose, and a leading producer of whey protein. Still owned by Jim and the Leprino family, our sights are set to be the “World’s Best Dairy Food and Ingredient Company.” A motivated team member who is the best at what you do. Three passionate individuals in a small corner grocery store in the early 1950s have now grown to well over 5,000 employees throughout the globe.
