Formally trained in conservation and restoration at the venerable West Dean College in Sussex, Jonathan Burden is always on the hunt for antiques and works of art to add to the striking and eclectic collection that has made his eponymous Tribeca gallery a favorite of leading interior designers. When he can’t find the perfect piece, he makes it himself, in collaboration with local artists, blacksmiths, ceramicists, glass blowers, and cabinetmakers.
