After studying at Harrow School of Art in the 1960s, Sue worked as a freelance illustrator. She moved to Cornwall in 1975, teaching printmaking at Penzance School of Art. In 1989 she moved to St Martins on the Isles of Scilly where she had her own gallery. Since 2006 she has lived in West Penwith. Her ink-and-watercolour sketches of local scenes have great popular appeal. A great number of her journals and sketches have been published in book form and are widely available in bookshops and art galleries throughout Cornwall and Devon. She says: 'I want to record the experience of living on the edge of the land, whether in Scilly, Penwith, or my new-found love and inspiration, Shetland.'

Sue runs a variety of courses and workshops covering a wide range of media.
