He was described as "the premier "power" surfer of his era [who] dominated the North Shore during the mid to late-seventies". He returned to Australia in 1986 where he farmed at Margaret River, Western Australia. In 1996 he returned to California where he now lives with his wife Alisa Schwarzstein, his son Jonathon (daughter Amy lives in Australia) and twin sons.
