Mr. Hartle is a fantastic teacher. Even in his old age (just kidding, he's not that old!), he teaches with passion and energy. He explains things so well with clarity and integrity-- he can make a student in the 60s rocket up to the 90s. His sense of humour is excellent. If you thought math was boring, you WILL change your opinion once you get taught under Master Hartle. He will be the first teacher I will miss once I graduate or once he retires.
He helped me actually understand math
One of the best teachers I had in my 4 years at Massey, highly recommend!
The best teacher I ever had! He is just awesome
Best math teacher I've ever had. I've always looked forward to his classes because he makes it really fun! He knows his stuff and is always there if you need help with anything.

A funny guy and a great teacher. Always willing to help students outside of class. One of those teachers that you feel grateful to after you finish their class.
