A recognized leader in Lean methodologies and strategic sourcing, Terri has built her career helping organizations reduce waste, strengthen processes, and achieve measurable, sustainable performance improvements.

Terri’s experience spans global organizations in manufacturing, medical systems, and industrial operations. She has led high-impact sourcing strategies, managed multimillion-dollar spend portfolios, optimized global distribution networks, and driven end-to-end process improvements across complex supply chains. At Bettcher Industries, she led a multidisciplinary team supporting strategic materials planning and supplier management for a private equity–owned manufacturing operation, delivering over $800K in annual cost savings and spearheading risk-mitigation, sourcing, and inventory optimization initiatives.

During her 14-year tenure at Varian, a Siemens Healthineers company, Terri served in progressive global supply chain roles, ultimately acting as a Lean Site Leader responsible for continuous improvement strategy. She managed global replenishment, reverse logistics, ECO processes, spare parts planning, and supplier performance across a worldwide network.

Terri is known for her ability to diagnose root causes, design practical solutions, and engage teams at every level, from frontline staff to executive leadership. Her approach blends Lean Six Sigma discipline, data-driven decision-making, and a deep understanding of supply chain dynamics combined with training, coaching and interactive simulations. She has successfully implemented value stream mapping, A3 systems thinking, strategic sourcing optimization, and process redesign across operations of all sizes.

A continual learner and passionate mentor, Terri has developed and taught APICS/ASCM curriculum as a CPIM instructor, and currently serves as Chapter President of ASCM Cleveland, leading education and professional development initiatives within the regional supply chain community.
