RPM Names David C. Dennsteadt as President and Chief Operating Officer
MEDINA, Ohio – July 17, 2026 – RPM International Inc. (NYSE: RPM) today announced that David C. Dennsteadt has been named president and chief operating officer for RPM, effective July 17, 2026.
Dennsteadt joined RPM’s Stonhard business in 1995 as an engineer, holding a variety of leadership roles, ultimately serving as group president of RPM’s Performance Coatings Group (PCG) from 2018 to 2025, where he delivered consistent growth and record results. He was elected RPM executive vice president in 2025, overseeing all corporate administrative functions. His global perspective, gained from years of leadership in Europe and the Middle East and in establishing RPM’s Platform Group approach to strengthening the company’s position in emerging markets, has been instrumental in driving strategic growth across RPM’s portfolio. In his new role, Dennsteadt will add responsibility for strategy and oversight of RPM’s operating groups, as well as corporate development activities. Dennsteadt holds a bachelor’s degree in civil engineering from Rutgers University and an MBA from New York University’s Stern School of Business.
RPM chairman and CEO Frank Sullivan stated, “Dave has consistently demonstrated the leadership and strategic vision that RPM needs as we continue to grow. His impact has gone well beyond PCG by having the foresight to drive greater coordination and efficiency across RPM’s international operations, and create a new approach to shared services, anchored by the centers he established in Mexico and India that now support the entire company. I’m confident he will bring that same discipline and vision to his expanded role as we build a stronger, more connected RPM.”
