Before joining Sam’s Club, Diana began her career at Walmart 18 years ago as a replenishment trainee in consumables. During her time in replenishment, she partnered with supply chain closely to create new inventory flow methods. She has also led various merchandising teams, which enabled her to develop a deep understanding of omni merchandising and product development across multiple areas in general merchandise and consumables.
Most recently, Diana served as the executive vice president of the Southwest Business Unit for Walmart U.S. operations. There, she oversaw five regions across 12 states, including some 750 Supercenters and 225,000 associates. In addition, she had responsibility for the Walmart+ store experience and operations oversight for the Dallas Innovation Hub for end-to-end transformation.
Diana has an extensive background in business and supply chain management, earning her bachelor’s in business administration from Oklahoma State University and her master’s in operations management from the University of Arkansas.
Diana currently sits on the national board of directors for NextUp, a nonprofit working to advance all women in business, and is an executive advisor to the NextUp Northwest Arkansas region, where she is an active member of the community. She also is a member of the Walton Arts Center board with a passion for the arts and theatre industry.
