Dollar General has elevated Chad Fox to the role of senior vice president and chief marketing officer as well as expanded his responsibilities to include management of the discount retailer’s digital team, according to a Tuesday emailed announcement.

In his higher-profile role, Fox, who joined the chain in 2019 as vice president and chief marketing officer, oversees Dollar General’s retail media network and will “continue his leadership and branding expertise to strengthen the voice of the customer, generate increased traffic and improve customer engagement,” the company said in a statement.

Fox spent more than 13 years in multiple positions at Walmart before joining Dollar General, according to his LinkedIn profile.

Dollar General has run a retail media network since 2018 and upgraded the platform last year to bring in more business from brands interested in reaching the retailer’s rural customer base. 

Dollar General also said Tuesday that it has hired Smriti Maheshwari as vice president of inventory and demand management. In that role, Maheshwari, who formerly worked at hardware retailer Lowe’s per her LinkedIn profile, will oversee the inventory teams for Dollar General’s consumables business, which has played a key role in driving the company’s performance in recent quarters.

In addition to bringing Maheshwari onboard and promoting Fox, Dollar General promoted Aaron Carlisle to vice president of asset protection.

The retailer also promoted Tim Bartlett, Julie Martin and Mark Person to the role of division vice president of store operations. Bartlett will be responsible for stores from Oklahoma to California; Martin will handle locations in Florida, Georgia, Alabama and Mississippi; and Person will supervise stores in Kentucky, Indiana, Ohio, Pennsylvania, West Virginia and New York, Dollar General said.
