When it comes to standing up for the arts in Atlanta, the key is putting your money where your mouth is. No one is in a better position to do that than LISA CREMIN, founding director of the Metropolitan Atlanta Arts Fund. Supporters cite her uncanny ability to target specific needs among specific arts organizations more often in the small to midsize range to prevent an arts community polarized into the haves and the have-nots. The feather in the cap: As a board member of the national Grantmakers in the Arts, Cremin was instrumental in helping bring the organization's annual convention to Atlanta in mid-October. Throw in MAAF's doling out $4.1 million to more than 60 Atlanta arts groups, and you have a true advocate for the arts. www.metroatlantaartsfund.org.
