Teresa Wicksteed was born in Sussex and educated in London. From the University of Leeds she attained a BA (Hons) in English, followed by an MA. Subsequently she obtained a PGCE in London, where she had a wide-ranging teaching career. She moved to the Rame peninsula in south-east Cornwall in the early 1990s. In 2002 she graduated from Falmouth College of Arts with a BA (Hons) in Fine Art. A fellow student at Falmouth was Moreen MOSS, who became a close friend.

Teresa works from a studio overlooking the sea. Her work is concerned with 'the immaterial, rather than the material world'. She says: 'The daily changes of light on the water feed my inner vision. I try to express in paint the transformative energy of my personal spiritual journey'. She describes her painting as 'a process of concealment and revelation'.

She has exhibited widely in both group and solo shows in Devon, Cornwall and London. Many of her works have found homes in therapeutic locations such as an osteopathy practice, an acupuncture practice, a yoga teaching room and two hospices.
