Gill started out as a painter and spent a year at the Slade School of Fine Art in London, but always had an interest in ceramics, including time at the Chelsea Pottery, before taking up a career in medicine.
On moving to South Wales, she followed a course at Swansea University given by the sculptor Gillian Still, and managed to combine some time for ceramics with her medical practice. Since retiring she has been making wall plaques, combining representational images with low relief modelling of earthenware and stoneware and in a novel technique using porcelain decorated with fusing glass.
