Although she didn't start her formal real estate career until 2003 with Allan Schneider Associates, now The Corcoran Group, Jaime has always possessed a keen knowledge of buying and selling real estate in the Hamptons. Being raised in an East Hampton home where both parents were top-producing brokers, arriving at The Corcoran Group was no accident. “It’s as though I had a master’s degree in Hamptons real estate by the time I was 18-years-old,” laughs Castantine, as she recalls a typical conversation at her family dinner table. After earning degrees in Business Management and Accounting at a small woman’s college in Boston, Jaime joined the management team at PAR East Mortgage in East Hampton, where she was afforded a further education into the ‘finance side’ of a real estate transaction. A few years later, Jaime decided to try her hand in sales by joining Gary DePersia, as his sales assistant.
