The International Brain Tumour Alliance is primarily a voluntary organisation with no current employees. We commission outside, paid-for services where necessary. The IBTA’s international secretariat is based in the UK and an active and highly motivated community of advisors in Australia, New Zealand, the USA, Canada and the UK provide additional support. Pro bono legal, editorial and accountancy services are provided by expert professionals. Other volunteers, supporters and IBTA ambassadors are dispersed across the world. We are grateful to them all for the tremendous and determined work they do.
