Mr. Alves will become the first non-family member to lead DiamondChem, succeeding Harold Diamond, who will continue to serve as a partner and strategic advisor to the company during this transition.
Decades of experience
Mr. Alves brings more than two decades of global leadership experience in industrial manufacturing and operations, including his most recent role as President & CEO – Americas at Armor-IIMAK, a multinational technology and materials group focused on Thermal Transfer ribbons. There, he oversaw operations spanning the Americas, with full P&L responsibility for a $200 million business and a workforce of more than 1,000 employees.

A strong legacy
Mr. Alves will work closely with Mr. Diamond over the coming months to ensure a seamless transition, building upon the strong foundation that Harold and the team have built over many years.
“I’m honored to join a company with such a strong legacy and excited to partner with the team as we move into our next phase,” said Mr. Alves. “Harold’s leadership has been instrumental in building a strong foundation with high potential, and I look forward to working together to continue that momentum.”
Diamond was founded in 1930 by Mr. Diamond’s grandfather. Since taking over the business in the 1980s from his father, Mr. Diamond has built DiamondChem into a leading provider of cleaning chemicals, with operations on the East and West coasts and sales throughout the U.S.
