Stephen Delo

Senior Advisor to the CEO

As the former chairman and CEO of HWI, Stephen Delo committed himself to strengthening the bond between HWI, its people, and its customers, and developing innovative ways to meet customers’ needs. Under Delo’s leadership at HWI, in less than four years, the company combined three of the top U.S. refractories companies together as one, and reorganized and rebranded as HarbisonWalker International. During that time, the organization restructured and built exceptional, high performing teams. Steve served as the director of integrated supply chain for Honeywell International’s performance, materials, and technologies business, and he held senior leadership roles of increasing responsibility during his 34-year tenure with Honeywell. Steve has a bachelor’s degree in chemical engineering and an MBA from Louisiana State University.

Steve continues to work intensely every day to transform HWI’s operations and drive long-term growth and sustainability through the transition of the CEO position to Carol R. Jackson.
