Critically-acclaimed director Sinéad O’Neill works internationally across opera and theatre disciplines, driven by a passion for fresh, direct storytelling. Her style is characterised by the poetry of body, voice and space, reflected in distinctive movement, striking imagery, and dynamic musicality. 


Sinéad’s background in music is present in all her work. Her first degree, in Music and French, is from University College Cork; she also holds a Masters in Musicology from University of Oxford and a PhD from Queen Mary University of London.


Sinéad’s portfolio ranges from co-creating original theatre to directing repertory opera. For Glyndebourne she has directed revivals of L’elisir d’amore and Il barbiere di Siviglia, the Glyndebourne Opera Cup, BBC Proms semi-stagings, 50th Anniversary Tour Concert, as well as assisting directors including Barrie Kosky, Annabel Arden, Stefan Herheim and Tom Cairns.


Sinéad has written and directed new works with composers Matt Rogers, Kate Whitley, and Kim Ashton. She founded Cambridge City Opera to create original music theatre for new audiences, with projects such as The Barrington Hippo and On the Axis of this World showcased at Cambridge Science Festival.


In rehearsal, Sinéad holds, translates and directs the energy of all those present, creating stagings that liberate the performer and give the audience a direct, intense theatrical experience. She enables her whole team, comprised of designers, performers and technicians to make committed theatre. 

Sinéad’s production of La Calisto was at Project Arts Centre, Dublin, in January 2020. Precipice, an immersive, site specific promenade was at The Grange Festival in August 2020. Pay the Piper was performed by Glyndebourne Youth Opera in February 2022.
