The Board operates as four directorates, each with a responsible executive director, in addition to a non-executive director, lay member and patient representative. The Board has authority on decision making within the Alliance.

Our member practices, via their nominated Practice Lead, have the overall influence on the direction of the Alliance and meet quarterly to review progress.

The Chair has oversight for all areas and the casting vote in board meetings.
