Board of Trustees

The Board of Trustees is the governing body that administers the charity. Our Board of Trustees guides the direction and management of the charity and all major decisions are made by the Board. They work closely with staff and meet regularly throughout the year to review and formulate strategies and policies for all areas of the organisation.

Chair of Trustees, Professor Croisdale-Appleby says:

I feel passionate about making the care and support provided by Admiral Nurses available to many more families affected by dementia. I am committed to ensuring that Dementia UK will play an influential role in the future of dementia care on a national and local level.
