There was a lot of good news in downtown Fort Worth this past week surrounding Friday’s opening of the new Sundance Square Plaza, but some of the best involved welcoming home an old friend.Well, sort of. On Tuesday, RadioShack opened its concept store in the new Commerce Building, one of the new structures built as book-ends for the plaza. RadioShack’s headquarters are not far away along the banks of the Trinity River.Surrounded by civic leaders and others at the event was RadioShack CEO Joe Magnacca, who joined the company in February with a mission of turning around its disappointing financial results of recent years.Magnacca may still be new to Fort Worth, but RadioShack is an old hometown friend, the offspring of companies founded here in 1919. In fact, among the local civic leaders at the store opening were two of RadioShack’s former CEOs, John Roach and Len Roberts.Along with an extreme makeover of RadioShack’s business, Magnacca has made it clear that he also wants to bring about a rebirth of the company’s leadership role in the Fort Worth community. That was music to the ears of those who gathered to help launch the new store.RadioShack’s local involvement, personified by Roach when he headed the company (a role from which he has not retreated even though he retired in 1999), has been missed in recent years as other executives focused more on internal corporate strategies.Some analysts have cast doubt on RadioShack’s turnaround prospects. But this is a company that, through its long history, has undergone rebirth after rebirth.That’s the way businesses survive, with the right leaders.Magnacca has found open arms with his plans to reconnect RadioShack with Fort Worth. He’ll also find people who will cheer for his local company.
