- 1994 to 2023

I taught history at San Diego Grammar School in San Diego from 1994 to 2023. Most days I taught primary school children, and I wrote a short note to every student at the end of term.
Outside the classroom I make terrible puns. Inside it, I wrote a short note to every student at the end of term.
Subjects taught
What gifts mean to Mr. Callahan: A gift would go toward books and supplies for the students I still tutor.
