🤩 Week 1 and our students are already learning the life skills that will help make them better. Every OTHS student is learning CPR. Putting their skills to the test, our Physical Education teachers guide them on the ABC’s of saving a life. It’s a great day to be a Panther.

Just another example of our staff Elevating Every Student! 💙
