John Deere Landscapes (JDL) appointed Doug Black to CEO.

Black joins JDL from Atlanta-based Oldcastle, a $12.6 billion building materials manufacturer and distributor and subsidiary of CRH, which is a supplier to JDL.

“Doug is a proven leader and a world-class business builder who understands JDL’s business model,” said Paul Pressler, chairman of JDL and an operating partner at Clayton Dubilier & Rice (CD&R). “He brings highly relevant experience in the materials, products and distribution sectors, as well as a track record of developing strong management teams and executing profitable growth strategies.”

During his 18-year tenure at Oldcastle, Black served as CEO and COO at Oldcastle Materials and Oldcastle Architectural Products. In addition, he was president of Oldcastle Precast southeast division and, as VP development for Oldcastle, established Oldcastle’s distribution division with the acquisition of Allied Building Products.  Prior to Oldcastle, Black was with McKinsey & Co. and the U.S. Army Engineer Corps.

“I am extremely honored and excited to be leading JDL as the company moves to the next level of profitable growth as an independent enterprise,” Black said. “JDL is extremely well positioned to leverage its industry leadership in rewarding new ways, while maintaining its exceptional customer service levels.”

Black succeeds David Werning, who will serve as an adviser to the business until his retirement at the end of 2014.

“With my eventual retirement, the search process was a priority and one that I envisioned to be somewhat lengthy,” Werning said. “When Doug Black emerged, we knew we had the right leader.”

Black is a graduate of the U. S. Military Academy (West Point) with a B.A. in mathematical sciences. He also holds an M.B.A. from Duke University.
