Grupo Cementos de Chihuahua (GCC) announced the appointment of former Lafarge Canada president and CEO Bob Cartmel as vice president of U.S. ready mix and Doug Roark as vice president of U.S. cement operations.

Cartmel joined GCC in November 2019 from his consulting business.

“Bob’s day-to-day operational knowledge is matched by his vision and passion to build stronger, more cost-effective companies,” said Ron Henley, president, GCC of America.

In Roark’s 14 years with the producer, he has served as vice president of ready mix and as vice president of energy and environmental. In his new role, Roark’s responsibilities include managing cement operations at GCC’s five U.S. cement plants. His experience in cement operations, environmental and ready mix bring great perspective to this position. Roark holds a chemical engineering degree from Oklahoma University and an MBA from the University of Texas at Arlington.

“Doug’s experience and knowledge across the GCC business and operations will help us build an even stronger company focused on serving our customers and operating in a more sustainable manner,” said Henley.
