Ren's P.E. teacher and baseball coach. "Coach Tee", as the others refer to him is a tough but fair and seemingly unshakable man who demands the best of everybody and is actually able to motivate people into giving that best. He has a keen eye for slackers and doesn't shy away from making them suffer, though he firmly believes in second and third chances. He  seem to have some worries outside from school and is sometimes late, or even has to be excused for personal matters, but that doesn't really seem to affect his work. Strangely, he is also not one of the teachers to switch to Jorgensen High next year.
