Strong was a painter who often showed with her husband, Henry ISRAEL, and the North Cornwall Seven group of artists. The couple moved to Cornwall in 1962, settling in Tintagel.

She studied at St Martins School of Art and the Royal College of Art, graduating in 1961 and in the same year first exhibiting in the Young Contemporaries Show at the RBA, London. After raising four children she returned to painting in the mid-1980s, a frequent exhibitor for the next 20 years.

Working direct from life in oils on canvas or board, her paintings were, on the surface, concerned with the quality of light falling across a landscape or still life. The apparent simplicity of the approach often masked greater depths of meaning hidden within the arrangement of objects or the way creatures and human figures, or evidence of their activities, appear in a landscape.
