Atmos Energy Corporation (NYSE: ATO) said today that effective December 31, 2016, Marvin L. Sweetin, Senior Vice President, Safety and Enterprise Services will retire to take a more active role in his family's businesses. "For more than 16 years, Atmos Energy employees have had the special pleasure of enjoying Marvin's friendship, leadership and support. Marvin has provided a steady hand and contributed to many successes in a variety of important leadership roles," said Kim Cocklin, Chief Executive Officer of Atmos Energy Corporation. "We wish Marvin and his wife, Regina, continued health, happiness and much success in the years ahead," Cocklin concluded. Sweetin joined Atmos Energy in 2000 as Director of Procurement and established the efficient warehouse supply and equipment model still employed today. He was named Director of Technical Training in 2007, Vice President of Customer Service in 2010 and promoted to Senior Vice President of Utility Operations in 2011, serving in that role until 2015.
