Forsyth County, GA, is evolving into a regional healthcare hub, with an expanding campus of Northside Hospital in Cumming and access to an Emory hospital in nearby Johns Creek. Children's Healthcare of Atlanta also zeroed in on Forsyth County this summer as it plunked down $17 million for property in the county. Healthcare now appears to be the fastest-growing industry in this rural-turned-wealthy suburban county, and its growth has closely tracked the county's population boom.
