Trustees Our Trustees govern, advise and determine the strategic and social aims of the organisation. The Trustees are volunteers from all walks of life but share a common goal of delivering and developing a centre of excellent, safe and effective treatment. Our Chair of Trustees is Dr Ian H MacLean. Dr MacLean was Director of Public Health in Dumfries & Galloway prior to taking up post as Chief Medical Officer and Director of Public Health in the Isle of Man. Dr MacLean is now retired from the medical profession.
