Home Depot is replacing its executive in charge of U.S. stores, veteran Marc Powers, with another longtime employee who rose through the ranks.

The Atlanta company told employees late last week that Ann-Marie Campbell, 50, will replace Powers, 54, as executive vice president of Home Depot’s U.S. stores on Feb. 1.

A Home Depot spokesman described Powers’ departure as “a mutual decision” but did not elaborate on the reason.

“It’s not surprising that Marc would be leaving after a long and successful career at Home Depot,” the spokesman, Stephen Holmes, said. He declined to say whether Powers, who started in 1986 as a salesman in a Home Depot store’s plumbing department, is taking early retirement.

Campbell has been president of the chain’s southern division, which includes about 690 stores in 15 states plus Puerto Rico and St. Thomas in the U.S. Virgin Islands. The Georgia State University grad, who has a degree in philosophy and an MBA, started as a cashier in 1985.

Last year, Campbell told The Atlanta Journal-Constitution that she learned much of what she knows about business from her grandmother in Jamaica, who didn't finish high school but turned a roadside business into a multimillion-dollar company.

“I learned a lot about commitment to family and commitment to winning. She had very high standards,” Campbell told the AJC.

In her new job Campbell will oversee about 2,000 stores and the bulk of the retailer’s nearly 400,000 employees.

Powers was named executive vice president of Home Depot’s U.S. stores in 2014 after the previous head of U.S. stores, Marvin Ellison, left to become J.C. Penney’s chief executive.

Current Home Depot Chairman and CEO Craig Menear also led U.S. stores, though with the title of president and expanded duties, before being promoted to the top corporate job in late 2014.
