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.

Early Childhood Director

Lorna Vander Sluis

“I am a follower of Jesus Christ who showed us how to love. My prayer is that every child who enters my classroom will experience the love of God through the words I speak and the actions that I take throughout the day. Every person who comes into my room is an image bearer of God and is worthy of God’s great love which must always be shown in my room.” Those who know Lorna well describe her as creative, inclusive, and kind.
