Our Governors

Since April 2008, TreeHouse School has been a Non Maintained Special School. This is a type of special school run by a charity rather than a local authority, which can receive certain types of Government funding. The Governing Body is separate from, but over-lapping with, the Board of Trustees in that two Governors are also Trustees and the Trustees receive reports from the Governing Body.  By law we do everything that a Governing Body does in a local authority school except manage the budget and the premises.

The Governing Body meets six times in the year but Governors are also actively involved in many aspects of school life. They are completely committed to the success of the school and to ensuring the best possible provision for our pupils.

Here is the Governing Body Code of Conduct.


Martyn Craddock - Chair of Governors

Martyn has been on the TreeHouse Governing body since December 2017 and is now chair of the Governing body. Martyn Craddock is the father of twin boys, one of whom has attended TreeHouse School since 2009. As a parent, he has an understanding of the demands and joys of being a dad of a child with autism, and the impact it has on his family's life. After an early background in catering, Martyn then moved into the charity sector, firstly working for one of the City of London livery companies, and then Finance Director and CEO of St Luke's Trust in Islington. In 2015 he became CEO of United St Saviour's Charity, a large grant-making trust and sheltered housing provider in Southwark.
