Great history teacher changed teacher to him in 3rd year went from failing to a B in the JC. Amazing geography teacher too. He's also very kind and caring towards students and always looks out for the ones he knows are having a tough time.
Sound teacher. Kind and understanding, always willing to listen.
Mr. O Callaghan was my favorite teacher at school for a myriad of reasons. Firstly, he actually knew what he was talking about - he taught with enthusiasm and passion. He counted each student for who they were, adapting the way he taught to address the needs each individual, taking in to account beliefs and opinions and working collaboratively with them. We related to him, he was real and down to earth, we could have a laugh. We respected him because he respected us. Thanks for everything OC.
Excellent Geography teacher! But thinks he owns the school and is way to strict tries to take control of everything and too many stupid rules!
