Who was your most influential teacher?

I don't have a most influential teacher, I have a most influential staff member, but no teacher. my most influential staff member is Dr. Plum our Principal. I believe that he has had the most impact on me since about the 5th grade. he has believed in me since he has known me, and he has given me a leadership role in the high school. he has also taught me many positive things, so I guess he is my most influential teacher.
