Guests entered the Land of Oz as soon as they walked into the Marriott St. Louis Grand Downtown. Greeted by several Dorothys, guests enjoyed cocktails, hors doeuvres and had pictures taken in front of Auntie Em’s house, on top of the Wicked Witch of the East, along with the Tin Man, the Cowardly Lion and the Scarecrow. Guests meanwhile were delighting in the antics of the flying monkeys. The Scarecrow led the way down the yellow brick road and upstairs into the ballroom which was turned into the Emerald City. Frank Cusumano led the program as master of ceremonies before guests danced into the night. In the last 12 years the Mercy Masquerade has raised over six million dollars for the Mercy Health Foundation, providing for the needs of children and adults in St. Louis who are uninsured and underinsured.
