Hotel Update: Radisson Blu

David P. Berg is late to our phone interview. But he offers a good excuse: He was wrapping up one of his “Donuts with David” sessions. Since joining Carlson Rezidor Hotel Group in December 2014, the company’s chief executive officer has sat down with groups of employees to hear their input on everything from what they think about the business to uniform design. “Our belief is in the wisdom of the crowd. They are so much better informed than us,” he says. “Instead of sitting around trying to figure it out or second-guess, why not ask the employees what they want and need? What is precious and what would they change?”
