Mr. Callahan is a fantastic and passionate history teacher. He knows the subject extremely well and is a great lecturer. Seeing as it is an APUSH class, it is rather difficult in terms of testing, and requires many hours of homework, but having him as a teacher motivated me to do well during both semesters of my junior year. He also has great style and a variety of awesome shoes. Mr. Callahan is in my top 5 for teachers so far.
Psychology. Super cool, super funny, easy class, easy to get along with.
Best teacher I've ever had. Callahan has the best stories, and they're always relevant!

He has the greatest stories...and I still remember so much of what I learned in that class!
