Abstract: An automated coaching service executes one or more coaches for a health service user. The coaches evaluate expressions created in part from a current user status and evaluate whether any actions should be taken for the user. Once an action has been performed, the status of the user is updated and taken into account the next time user coaches are executed. Actions performed by health coach service coaches can be directed to a user or a health care professional. The health coach service can provide a dynamic coaching mechanism to the user that provides custom coaching based on the most current user health data and recent actions performed for the user.
