We were very fortunate to have an exceptional leader like Jim at the helm as the Company navigated during the pandemic,” Mr. Krenicki continued.

“Rose is a proven leader and team builder with a diverse and deep set of skills and experiences. She and Jim share a common belief that talent, team and customers are the keys to success. The board is excited to have Rose join and lead Cornerstone Building Brands and work closely with Jim to ensure a seamless transition,” concluded Mr. Krenicki.
