The Buckhead Coalition celebrated its 25-year anniversary with a social event this month called the President’s Luncheon. Gathering at the St. Regis Hotel, the nonprofit’s founding president, Sam Massell, singled out the group’s founders and former chairpersons to express thanks. A 1988 – 2013 anniversary booklet contained highlights from the civic group’s history: lobbying the Atlanta City Council to approve the construction of Ga. 400 through Buckhead, installing a network of free-standing 911 emergency telephones, paying $50,000 for information leading to the arrest and conviction of a murderer, and placing defibrillators where people congregate — including churches, hotels and office buildings — rather than on ambulances that might be slowed by heavy traffic.
