Meet the Fair's Ambassadors

Treasure House Fair engages with the international art community while connecting with the creative minds shaping the industry. We are delighted to introduce our Fair and Media Ambassadors, a group of individuals with expertise in varied fields who will help shape how fairs will evolve in the future.

They are a source of inspiration to us, a voice of advice, and above all, friends of the fair. Through their diverse perspectives, they connect us with wider audiences and help bring fresh ideas on how to build a strong fair while continuing to honour the 90 year tradition of London summer art fairs.
