As a musical director Cillian has enjoyed working with various different groups and ensembles including performers from Guildford School of Acting, Dutch Academy of Performing Arts, British Youth Music Theatre UK and Royal Northern College of Music Young Company.
As both a classical and musical theatre singer himself, he enjoys working with casts on various different styles of the musical theatre repertoire. He has been fortunate enough to work on popular pieces of the musical theatre cannon as well working on original productions, which included directing the live cast recording of Pippa Cleary's Tess of the d'Urbervilles.
Outside of productions Cillian has lead various ensembles including Macclesfield Mydel Ladies choir and the University of Manchester Medic's Orchestra and Choir. He has also assisted rehearsals of Holy Cross Chamber Choir, Hallé Youth Choir and Hallé Youth Training Choir.
