Bikes for Refugees

Our Middle School students in the Bikes for Refugees Changemaker Activity developed their practical bike repair skills and showcased exceptional dedication. Last Friday, they presented the repaired bikes to refugee children at OeSA, sparking immense joy as the children received and learned to ride them. This amazing event showed the significant impact of community support. We hope our students will continue to embody the generosity and empathy they have demonstrated, leaving a lasting positive influence on our community.
