The most impacting teachers were the ones I found at community college. Mrs. Buckman was and is the most influential teacher I ever had. She gave using what she taught a new definition. Everything that woman studied, she used in her life and in her classroom. I've always admired her strength, ability to balance work and family, as well as devotion to her job.
However, in high school, there were a few teachers that helped me such as Mr. Garrett. He helped me understand philosophy and public speaking and made me comfortable around others (kind of necessary for a homeschooler to learn).
