Cardiff High School was my second home. I taught mathematics there from 1988 to 2016, mostly Year 9.
Over the years I had 1,460 students pass through my room. A few of them became teachers themselves, which still makes me smile.
More about Mr. Callahan
The students I remember best weren't always the top of the class. They were the ones who asked "why?" when nobody else did.

What gifts mean to Mr. Callahan: Honestly the messages mean more, but a gift would help me buy supplies for my new classroom.
