The British Association of Dermatologists is the professional organisation for Consultant, Trainee and Staff and Associate Specialist dermatologists in the UK and Eire. Established in 1920, it is a registered charity with an incorporated body of trustees, the Executive Committee, who are all dermatologists elected by the membership. The Officers, supported by the professional staff carry out the day to day business from Willan House, the headquarters building in central London. The BAD has clear objectives which are set out in the Constitution and are taken forward by the business units and sub-committees. The BAD works with many other organisations to achieve its aims of supporting patients and improving standards. These include Patient Support Groups, Special Interest Groups, International Dermatology Groups and the Medical Royal Colleges.
