Continuous Improvement Manager at Plains Dairy
📍 Amarillo, Texas, United States

John is a manufacturing leader with over 17 years of experience in food packaging and medical devices. As a Continuous Improvement Manager at Plains Dairy, he focuses on developing CI programs. He holds a Certificate in Management from Stonehill College and a Master Molder I certification.

Outside of work, John values organization and planning, a habit he learned from his father. He uses a specific year-in-one-book Harvard Planner to maintain a long-term perspective on his schedules and tasks, preferring it over monthly planners.

He once diagnosed a catastrophic screw and barrel failure on a Uniloy 350R3 machine by noticing subtle signs like fluff and "fish eyes" in the product.
