All Denaro's small studies are painted on location on the Isle of Doagh, an island on the Atlantic coast of Ireland. Her larger oil paintings are inspired by these smaller studies and are usually painted in London. Denaro was trained at Central School of Art and the Royal Academy Schools. Her first exhibition at the gallery was held in February 2002.
