How do you make a good thing even better? Five hundred friends of Colorado Ballet did it by being part of a fundraising gala whose $300,000 net profit will help fund, among other things, a collaboration with Kansas City Ballet that will result in the creation of a new, full-length production of “The Wizard of Oz.” “This world premiere collaboration will further elevate Colorado Ballet’s national stature and fulfill on the promise of injecting fresh works into the repertoire of American ballet,” noted Jim Hillary, who with his wife, Anne, chaired “An Evening in Verona: A Romeo and Juliet Gala.” Jim Hillary is the principal and founding partner of Fios Capital.
