Lesley studied Fine Art at the Cape Technikon under Herbert Coetzee. She was later tutored by renowned local artists such as Joe Osser and Ryno Swart. In addition to being an accomplished artist in her own right, she is also known as an inspirational and highly sought after teacher. She facilitates workshops at her Montebello Studio and also leads five-day painting retreats in picturesque towns in the South African countryside. Lesley is regularly invited to art societies to demonstrate oil painting, colour mixing and compositional techniques. She has also illustrated several popular and acclaimed children's books. At the end of 2011 and 2016, she was selected to spend two months in residence with fellow international artists at a Parisian studio attached to the Cite International Des Artes. She used this opportunity to paint on the streets of Paris and enrol in the Académie de la Grande Chaumière. Lesley has been featured in the South African Artist Magazine and was chosen by the Swiss national airline, Edelweiss Air, to represent Cape Town on the pages of their in-flight magazine. She paints, teaches and exhibits her work at the Lesley Charnock Gallery, which is situated in the Montebello Design Centre, in Newlands, Cape Town. She is also represented by Top Galleries, and her work hangs in collections around the world.
