Compassionate leadership

Bringing strategy and kindness together

  • Transparency in vision. As a parent at Living Stones, you’ll be invited to hear from school leaders about the plans for the future and to approve the budgets.
  • High five! Children are greeted daily by school leaders and will know that they will be listened to and valued.
  • Supporting teachers is key. One of the top priorities of the board and leadership team is to empower and support teachers so they can shine and love your children well.
