Atlanta-based Prudential Georgia’s acquisition last week by a company with ties to business magnate Warren Buffett has stirred excitement among employees. “I am personally honored to be with such a well-known company,” said Kim Crumley, who manages Prudential’s Gainesville and Demorest offices, on Wednesday. HomeServices of America Inc. is an affiliate of Berkshire Hathaway, a multinational conglomerate holding company headed by Buffett.
