Mary Dillon is originally from Kilkenny, but moved to Roscrea in 1984. Mary has no formal training in art but has been painting for as long as she can remember. She first exhibited her work during Kilkenny Arts Week at the age of thirteen.
More recently the Bank of Ireland have added her work to their art collection, and five of her paintings belong in the OPW art collection. Her paintings now belong in many prestigious public and private art collections, including The Hodson Bay Hotel, Athlone, The Malton Hotel, Killarney, The Hibernian Hotel, Kilkenny, and Áras an Uachtaráin.
