Lee began her career as a designer, training at Central School of Art and Design, London.
After having children, she went back to college and began studying drawing and painting. She found herself to have an affinity with portraiture, and in the following years began taking commissions and entering competitions. In 2009 her portrait of Gail Porter was selected for the BP Portrait Award at the National Portrait Gallery.
It was in 2012 her portrait of Michael Rosen was also selected for the BP Portrait Award and then subsequently acquired for their Primary Collection. The portrait is normally on display there. Her work has also been included in Art UK, the online home of every public art collection in the UK.
In her garden studio, Lee has continued to produce drawings and paintings, as well as pastel landscapes of Blackheath and Greenwich. In her more recent series, she has explored abstracted landscapes in oils.
She also runs portrait and painting classes in her studio, as well as other workshops.
