Our Board of Directors
Our Board of Directors sets the overall strategic direction for the Trust and is collectively responsible for monitoring all aspects of performance, providing financial stewardship and ensuring the provision of high quality, safe and effective services.
The Executive Directors manage the day to day operational running of the organisation, whilst the Non-Executive Directors are focused on challenging the Executive Team on management and strategy. The Non-Executive Directors do not hold any managerial responsibility, but are accountable with the Executive Directors for the Trust’s performance. The contribution of Non-Executive Directors, and their relationships with Executive Directors and governors, is facilitated by the Chair.
All of our Non-Executive Directors are considered to be independent, as they have not been employed previously by the Trust and do not have any financial or other business interest in the organisation. Chrissie Cooke is our Senior Independent Director.
Details of our Board meetings, Agenda and Papers are available on this page: Board Meetings

The Board works closely with our Council of Governors to enable the governors to carry out their statutory duties. Governors’ views are sought on the Trust’s forward plans and the Board also provides feedback on the Trust’s undertakings and performance.
Our Council of Governors provide local accountability by representing the interests of members and partner organisations. The Board of Directors retains overall responsibility for decision-making, except where the Council of Governors has statutory responsibilities.
