Clean Harbors Appoints Robert Willett Chairman of the Board
NORWELL, Mass.–(BUSINESS WIRE)–Clean Harbors, Inc. (“Clean Harbors” or the “Company”) (NYSE: CLH) today announced that it has named Robert Willett as Chairman of the Board, effective immediately, completing the Board transition first announced in May when Founder and Executive Chairman Alan S. McKim communicated his intention to retire from the Board.
McKim’s decision to retire comes after more than four decades of service. McKim founded Clean Harbors in 1980 and led the Company’s growth and transformation into North America’s leading provider of environmental and industrial services.
Willett has been an independent member of the Clean Harbors board since 2019. He spent 14 years as Chief Executive Officer of Cognex Corporation, a global leader in machine vision systems, retiring in June 2025. During his tenure, Cognex significantly expanded its global footprint and nearly tripled its revenue.
“Rob has been a valuable member and strong contributor to the Clean Harbors board for the past seven years,” said McKim. “He has deep operational knowledge based on his decades working in the technology and automation space, as well as extensive public company and board experience from his years leading Cognex through a significant growth expansion phase. He is the ideal choice to lead the Board given his skillset. I fully expect Clean Harbors to continue to grow and thrive with Rob as Chairman, working closely with our co-CEOs Eric Gerstenberg and Mike Battles to execute our long-term vision. As I step back to spend more time with my family and pass the torch to the next generation of leaders, Clean Harbors’ mission to build a safer, cleaner environment remains unchanged.”
Willett serves on the boards of Formlabs, a private industrial 3D printing company, and Allegro MicroSystems (Nasdaq: ALGM), a global leader in sensing and power semiconductor solutions. Prior to joining Cognex, he served as Vice President of Business Development and Innovation for the Product Identification Business Group at Danaher Corporation, a diversified industrial company specializing in process improvement and acquisitions, and as President of Videojet Technologies, a leader in coding products. He previously was Chief Executive Officer of Willett International Ltd., a coding and marking company that was sold to Danaher and merged with Videojet. He received a bachelor’s degree from Brown University and an MBA from Yale University.
“We have worked closely with Rob in his role as an independent director and are excited to welcome him as Chairman,” said co-Chief Executive Officer Mike Battles. “Rob’s operating experience as a CEO, disciplined approach to capital allocation and strong understanding of our company and culture will be invaluable as we continue to execute our growth strategy and advance our industry leadership position.”
“Since joining our Board, Rob has been a highly engaged and thoughtful board member, contributing meaningfully to the development of our long-term strategy and governance framework,” said co-Chief Executive Officer Eric Gerstenberg. “His deep knowledge of Clean Harbors and contributions to our strategic and governance priorities will provide important continuity as he steps into this Board leadership position.”
