The concept behind Florida Hospital , Craig Ustler said, is that they want to keep people healthy. So it makes sense, he added, the Florida Hospital has expanded its base mission, and hired Ustler's development firm, Ustler Development, to construct something unique in College Park: apartments for the hospital's workers. "The hospital model is really shifting from getting paid to treat people when they get sick to getting paid for keeping people healthy," Ustler said. "They see building a complex in the neighborhood that can do all these things. For them, this is really where health care is going."
