BEST POWER FAMILY Los Valdes-Fauli When Raul Ernesto Valdes-Fauli died in 2003 at age 84, evidence of success in this life wasn't measured by the prominence and prosperity he had achieved as a former lawyer who represented banking and sugar interests in pre-Castro Cuba. (He was very prominent and prosperous.) No, it was the prominence and prosperity his children had gone on to achieve. The siblings didn't just sit on their trust funds; they clambered to the top of a variety of fields, mainly leaning toward endeavors connected to money and power. Son Raul J. is the former mayor of Coral Gables and now an attorney at Steel Hector & Davis. Another son, José, is Colonial Bank's South Florida regional president. A third son, Gonzalo, is a director at Knight Ridder who formerly headed Latin American operations for the Barclays banking organization. Daughter Teresa Weintraub is president of Fiduciary Trust International of the South.
