For 28 years I have been the biology teacher at Mississauga Public School. I teach the youngest children and a few brave older students who wanted extra help.
I've coached the school's cross-country squad for a few seasons. We lost more than we won, and I'd do it all again.
If we met, say hello. I'd love to know how life turned out.

What gifts mean to Mr. Callahan: A gift would go toward books and supplies for the students I still tutor.

I'm a pilot now and I honestly think it started in your classroom. Greetings from Joliet.
