Rosa has worked in senior leadership roles at a number of significant cultural organisations in the UK and Australia such as Bristol Beacon, Bournemouth Symphony Orchestra, Salisbury Festival, Arts About Manchester (now named The Audience Agency), Royal Northern Collage of Music, Sydney Symphony Orchestra, Musica Viva and others. She has been in her current role as Development Director for 11 years. The Bristol Beacon is noted for having changed its name from that of slave trader Edward Colston in 2020. This change has come at a time when the Victorian concert building is being completely transformed in the largest ever arts capital redevelopment in the south west of England.
