Though Irish, her career has mostly been in the British market, where she has amassed a long string of starring television roles. She has been a part of the regular casts of several British programmes like Goodnight Sweetheart, Eureka Street, Hearts and Bones, 55 Degrees North, and True Dare Kiss. She is likely most famous, however, for her National Television Award-winning role of Assumpta Fitzgerald in Ballykissangel, a role with which she crossed over into both The Vicar of Dibley and Father Ted.
