• Own and deliver large, cross-functional packaging capital projects from early design through startup.
• Lead system-level design of tertiary packaging lines, including case packers, palletizers, stretch wrappers, labeling, and integrated conveying systems.

Leprino’s history dates back to the 1950s, 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 is the world’s largest manufacturer of mozzarella and lactose, and a leading producer of whey protein. Still owned by the Leprino family, our sights are set to be the “World’s Best Dairy Food and Ingredient Company.”

From a small corner grocery store we have grown to over 5,500 employees throughout the globe. Will you join us on our journey?
