St. Mary’s Medical Center is truly a wonder of architecture. It may be the world’s first stealth hospital. It sits squarely in the center of San Francisco, just steps from the bustling Haight-Ashbury district, and yet, no one knows it’s there. So, when the time came to refresh their QuickCare campaign and primary doctor campaign — the only successful advertising they’d ever done – we knew we had to hit the audience hard. Possibly with a blunt object.
