Years Ago, Sons Traditionally Entered the Profession of Their Fathers

Years ago, sons traditionally entered the profession of their fathers. It has become much less commonplace today--but not for the Pulley family. The father Keith Pulley is a selling agent, a type of middlemen, and all four of his sons are also involved closely with distribution strategy. The oldest son Craig operates a manufacturer's sales office. George is a broker while Troy operates a trucking company. The youngest Jonathan runs a wholesale company that specializes in importing fresh-cut flowers.
