The American Cement Association (ACA) has confirmed Diane Tomb will take over as the association’s next president and chief executive officer.
Tomb joins the ACA from ACG Advocacy and has previous experience as the chief executive officer of the American Land Title Association, as president of the National Rental Home Council, and president and chief executive officer of the National Association of Women Business Owners.
“America’s cement industry is a foundational pillar of our national infrastructure, our manufacturing base, and our national security,” Tomb said.
“As innovation and technology reshape how we build from data centres to next-generation infrastructure, domestic cement production is central to America’s economic competitiveness. I am honoured to lead ACA at such a consequential moment and could not be more excited to get to work.”
She will work closely with the outgoing ACA president and chief executive officer Mike Ireland, during a handover period, with Ireland staying on the ACA staff until the end of the year.
“ACA’s strength has always come from its people, its mission, and its commitment to serving the industry with excellence,” Ireland said.
“It has been an honour to lead ACA throughout the past decade, and I am confident that under Diane’s leadership, ACA is well-positioned for continued growth and impact in the years ahead.”
Overall, Tomb has more than 25 years of experience in executive leadership and policy. She has served as the assistant secretary of public affairs at the US Department of Housing and Urban Development, the director of public affairs at the US Department of Commerce’s International Trade Administration, and in the White House.
“Diane brings strong leadership experience to ACA, a deep expertise in national trade associations, a long history of driving collaboration both within and across industries to create lasting value, with the proven ability to advocate effectively on Capitol Hill,” ACA board chair Monica Manolas said.
“She has an impressive track record of raising the profile of other respected trade associations, and I’m certain she will take ACA to the next level as well. I’m happy to welcome Diane to this role at this exciting time in the industry’s history.”
