Guide Dogs Chairman, Tony Aston OBE DL, has resigned from his post on the grounds of ill health. Tony Aston’s tenure was due to end at the July 2012 AGM but he has brought the date forward in light of medical advice. Tony, a guide dog owner, has served as a Trustee of Guide Dogs for nine years. He took up the role of Chairman in 2007. Deputy Chairman, Amos Miller, has assumed the Chairman’s duties until a new Chair is elected in July. Amos, who is also a guide dog owner, said: "Tony leaves the charity in great shape and his devotion to Guide Dogs has been exemplary." Rodney Buse has stepped down as Chairman Designate. Tony said: "I leave Guide Dogs with great sadness. This is a fantastic charity without which my life would have been significantly diminished. "Guide Dogs is a magnificent organisation. We have thousands of committed volunteers and supporters. I thank them for their dedication and recognise the vital role they play in helping blind and partially sighted people get out and about on their own terms. I wish them every success for the future." Chief Executive Richard Leaman said: "I am deeply saddened that Tony has had to curtail his time in charge of Guide Dogs. He has been a powerful and highly effective advocate for blind and partially sighted people for much of his life."
