After studying at Harrow School of Art in the 1960s, Sue first worked as a freelance illustrator. She moved to West Penwith in Cornwall in 1975, inspired by the wild and rugged land. She augmented her income as an artist by teaching printmaking at Penzance School of Art.
In 1989 she moved to St Martins on the Isles of Scilly, where she ran her own gallery. Here, she was surrounded by a completely different landscape from that of Cornwall; rocks, sand and sea, in its many moods. In 2006 she returned to live in West Penwith, working from a studio at her home and exhibiting in many galleries in the South West. 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 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.'
