Sally, the daughter of a British army officer, was born in Kingston, Jamaica. Depending on her father's army postings, she spent her formative years living in various countries, eventually the family settled in Sussex. Sally's artistic career began in the late 1970s. To support herself while in medical school, she used the pseudonym Heinrich Stoltz to draw animals. These sold through auction houses such as Bonhams, Sotheby's, and Christie's. A chance meeting at the Pavilion Gallery, owned by the Hughes-Hallett brothers, introduced her to Royal portrait painter John Hughes-Hallett. This meeting sparked a friendship that lasted over two decades. John Hallett, who studied at the Chelsea School of Art, was friends with the renowned British artist Claudia Williams, known for her large, colourful portraits. With John Hallett as her mentor, Sally focused on portraiture, she was commissioned to paint notable figures, including the President of Calvin Klein and French footballer Zinedine Zidane. However, her emphasis on portraiture was not permanent. In 2000, she received a commission to create a series of six large canvases, measuring 250 x 220 cm, that depicted the landscapes and colours of the South of France. The paintings took nearly four years to complete and now hang in a private museum in New York. In 2005, she exhibited at Frances Roden Fine Art in London and continues to showcase her work through international galleries today.
