It was 1959 and on the New Jersey shore a bright young man named Ron DiMenna was just discovering the sport of surfing with fiberglass surfboards. The pastime soon became a passion and homemade surfboards would no longer do. When his father heard that Ron wanted his own custom surfboard from California, he suggested, "Buy three, sell two at a profit, then yours will be free." His Dad was right and Ron Jon Surf Shop was born.
