I'd have to say Mr. Anthony Ragonese was my favorite.  He was witty, taught well, and had a firm grip on his class, to say the least.

Others right up there, though, include Mr. Jim Wesson, the 8th grade math teacher and Mr. Bob Garrett, who taught upper grade social studies.  Mr. Wesson's booming voice brought any upheavel under control quickly and Mr. Garrett really knew his stuff.
