Deepest condolences on the passing of Mr. Mark J. Byerley, Sr. The corrosion industry has lost a true pioneer and visionary leader. His contributions, mentorship, and dedication will never be forgotten. Rest in peace, and thank you for leaving such an enduring legacy.
AMPP is deeply saddened by the passing of Mark J. Byerley, Sr., President and CEO of Tinker & Rasor and a respected leader whose influence spanned generations of the corrosion control community.
Mark dedicated more than five decades to the industry, carrying forward a family legacy rooted in service, innovation, and relationships. His connection to NACE International began through his family, and he later served as NACE President from 2009 to 2010, following his father, Darrel D. Byerley, who served from 1974 to 1975.
Throughout his career, Mark helped advance corrosion prevention and materials protection while remaining deeply committed to the people who make this industry so special. His leadership, integrity, and stewardship left a lasting mark on Tinker & Rasor, AMPP, and the broader profession.
AMPP extends its heartfelt condolences to his wife, Denise; his son, Mark J. Byerley, Jr.; his daughter-in-law, Heather; and all of Mark’s family, friends, colleagues, and the entire Tinker & Rasor team.
Mark’s legacy will continue through the people he inspired, the relationships he built, and the industry he devoted his life to serving.
