Originally from Dublin, Ireland, Cathy began playing music with the Rathfarnham Concert Band Society located in Dublin, starting on the recorder when she was 8, and moving to the clarinet when she was 10.

A few years later, she joined their concert band where she says she got her first taste of playing in an ensemble. Other ensemble experience includes the National Youth Orchestra of Ireland, the Irish Youth Wind Ensemble, the European Youth Wind Ensemble and various orchestras and concert bands throughout Ireland. After completing her bachelor’s degree in music performance in Dublin, Cathy moved to Canada to further her Clarinet studies at the University of Montréal with André Moisan.

A founding member of the Milton Philharmonic Orchestra in 2014, Cathy joined the board of directors as their Marketing Manager in 2019 where she continued to perform with them until 2023.

In September 2023, Cathy joined the Cambridge Symphony Orchestra and in September 2024 she took on the role of Orchestra Manger for the CSO. Cathy frequently freelances in the GTA area and performs regularly with the Southern Ontario Lyric Opera Company (SOLO), Burlington Symphony Orchestra and as a substitute player for the Mississauga Symphony Orchestra.
