In October 2000, Stacey completed a Masters Degree in Fine Art Valuation at the Southampton Institute where he specialised in English eighteenth and early nineteenth-century watercolours and early twentieth-century European art. He has over a decade of experience working in the fine art market and has been employed by both major London auction houses and provincial auctioneers and galleries, including Christies, Bonhams and Brobury Art Gallery.

Now an independent art dealer based in Leominster, one of the country's leading centres of antique and fine art commerce, Stacey Williams stocks a extensive range of eighteenth, nineteenth and twentieth century prints, watercolours, oil paintings and sketches. He also acts as an agent for well-renowned local artist, Fiona Field.
