Fabulous presentation, with key takeaways and ability at our site, and be given time to do this.

Fantastic session, great honesty and sharing of the learnings that happened, would love to hear more.

This session has highlighted the need to revisit school vision and values, with staff, students, parents and two points really resonated, 1. What does it take for our minority voices to get on board? 2. How do staff know that they are being listened to?

The feedback from my leaders on the session Thilan presented was outstanding. It really hit the mark as PD for leaders and leadership development. It gave leaders time to reflect on their site culture and how they are building high performing teams. My leaders want Thilan back so they can explore her message even deeper.

This presentation was great. Teams should be encouraged to attend together.

Thilan is always a great presenter.

Keep on doing what you do so well Thilan. I hope that you take some time yourself and accept positive feedback about the wonderful impact that you have had in various places that you have been called to.
