OUR TEAM

Barnaby would like to spend most of his time on the water, but is prevented from doing so by a number of other commitments, in no particular order: job (fund manager); family (non-sailing); horse, dog, garden and, not least, Treebeard Trust. 

His personal mission is to break down the artificial barrier between philanthropy and business.
