Matty was born and raised in Australia, but found his way to Seattle 11 years ago and has recently moved back to Fremantle, Western Australia with his wife, son, daughter and dog. If Matty's not chasing (or being chased by) his two munchkins, he's drawing, and if he's not drawing then he can be found making something creative, and if he's not creating something then he is skateboarding, and if that's not the case then he is probably snuggling with his lovely wife on the couch watching TV.
