Una has been a professional artist all her life and held many exhibitions in Ireland, the United Kingdom and in New York.
A well known Limerick personality, Una has been a professional artist based in Ireland since she went to the Limerick School of Art, Ireland. She has created portraitures of famous faces from across the world, thrives in creating fun caricatures and adores the wildness of the Irish coast to inspire her landscape paintings. When she is not sketching on location, she mainly works in her studio in Limerick where she captures the magical atmosphere of Ireland. With corporate and private collectors from across the world adding her work to their collections, she continues to create new colourful energetic paintings and unique commissions.
