Senior Management Team

The Senior Management Team, chaired by the Chief Executive, brings together senior Executives including the Executive Directors to the Trust Board.  It is responsible for the implementation of Trust’s strategies and policies and for key operational matters.

Non Executive Directors are appointed to the Board through a Public Appointments process. This role ensures that people from all walks of life, not necessarily with a career path in health or social care, have an opportunity to play a part in managing public organisations like ours. They have a duty to uphold the principals of public life and represent the Trust to the wider public.
