ATLANTA, GA (August 8, 2023) – J.M. Huber Corporation, one of the largest family-owned companies in the United States, announced today that after 20 years with the Company, Chief Financial Officer (CFO) Jeff Prosinski will retire, effective January 1, 2024. He will be succeeded by Glenn M. Fish, effective August 21.  

Prosinski has served as Executive Vice President (EVP) & CFO of Huber since 2006. He joined the Company in 2003 as Vice President of Finance in charge of the Tax and Internal Audit Departments and was named Corporate Controller of Huber in 2004. He has served on the Management Boards of all three of Huber’s portfolio businesses, CP Kelco, Huber Engineered Materials and Huber Engineered Woods (HEW).
