Mark Grey is in The Hot Seat together with his assistant dog Hoover. Mark is vision impaired, and relies on his assistant dog to get around.  Mark is on several boards, such as the Tasmanian Public Trustee, and also St Giles, which is an important not-for-profit organisation in Launceston providing life solutions for people living with disability.

Mark is also the current chairman of Vision Australia, and frequently travels to Melbourne for Board meetings. But he has chosen to live in Launceston, and tells Chris Sayer why.
