His father Keith is also a highly regarded name in the sport across both South Africa and Australia.
Dean moved to Melbourne, Australia, at age 15, leaving most of his family behind. That move inspired his first original composition, a song called “Change,” which he wrote to process the experience of relocating from his homeland.
