Already wearing multiple hats as Best Buy’s head of U.S. retail and human resources, Ballard has gained even more responsibility at the Minneapolis-based retailer. In May she was named senior executive vice president, shedding her HR role but adding the Mexico business as well as real estate to her purview. Ballard, who started as an assistant store manager, now oversees some 1,400 Best Buy stores, accounting for over 80% of the company’s overall revenues. Sales fell slightly in fiscal 2016, to $39.5 billion, but beat investors’ expectations.
