Hannah Sonnenberg’s career has been shaped by a simple philosophy: understanding the entire process leads to better results. Long before joining IMT Elemental, she built a broad manufacturing background that exposed her to nearly every stage of production. At Welland Forge, she worked across inside sales, purchasing, production scheduling, and shipping, coordinating client orders, procuring raw materials, and working closely with production and quality teams to keep operations running smoothly. She later joined ArcelorMittal Dofasco, where she supported production through inventory management, material handling, and safe overhead crane operation — experience that further strengthened her understanding of manufacturing from the shop floor.
Today, as program supervisor at IMT Elemental, Hannah brings those experiences together in a role that requires equal parts organization, communication, and technical awareness. Her colleagues describe her as the critical connection between clients and internal operations, overseeing programs from quotation through final delivery while coordinating engineering, production, quality, and logistics. She thrives in an environment where every project depends on collaboration, ensuring client expectations are met while keeping work moving efficiently through the organization.
What stands out is her ability to build relationships. Whether working with clients or collaborating with coworkers across multiple departments, Hannah approaches challenges with professionalism, responsiveness, and a solutions-oriented mindset. Her broad manufacturing experience has given her an appreciation for every step in the process, allowing her to anticipate issues before they become problems and keep projects moving forward.
