set up in 2011, Treebeard Trust is a small foundation with big ambitions. 


We believe that society is broken and that the only way of fixing it is through a radical overhaul of old models – of philanthropy, of business and of public life.

We are growing! We now have three (nearly four watch this space) trustees and a part-time director. We recognise that our pot of money is small, but we intend to use it strategically to achieve lasting change.


THE TEAM

 

Barnaby Wiener, Founder and Trustee

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.

Cassandra Wiener, Founder and Trustee

Cassandra is a lawyer, initially training at Simmons & Simmons before leaving the city to teach law at the University of Law.  Currently she is finishing up her ESRC funded doctoral research at the University of Sussex looking at the criminal law in the context of domestic abuse, and working on a book for Routledge ‘Coercive Control and the Criminal Law’. Cassandra is passionate about all things Treebeard but her particular interests are in the areas of criminal justice and domestic abuse. 

 

Jessamy Gould, Director

Jessamy has worked in the charity sector for twelve years, fundraising from a range of sources including trusts, statutory and corporate. Most recently she headed up the corporate fundraising team at national education charity Teach First where she worked for five years before joining Treebeard as Director in October 2016. Jessamy has been involved in the trust since its inception, serving as a board member until early 2016. She runs Treebeard Trust from her home on the Suffolk coast where she lives with husband Matt and her two sons.
