GOODLETTSVILLE, Tenn. — Dollar General Corp. continues to shuffle its leadership ranks ahead of the planned retirement of chief executive officer Todd Vasos. The latest move involves a promotion for chief financial officer John Garratt, who on September 1 added the role of president.

The 53-year-old Garratt will remain responsible for the company’s finance, accounting, strategy and procurement functions. As president, he assumes responsibility for Dollar General’s strategic health care initiative and its international expansion to Mexico.

Garratt joined Dollar General in 2014 as senior vice president of finance and strategy and has served as executive vice president and CFO since 2015.

“John is an accomplished leader with exceptional business and financial acumen, as well as the strategic vision to support Dollar General’s long-term growth opportunities, and his appointment to president enhances our management structure as we continue to differentiate and distance Dollar General from the rest of the discount retail landscape,” said Jeff Owen, Dollar General’s chief operating officer.

Owen is slated to become CEO upon Vasos’s retirement, on November 1.
