Calculus teacher, senior year, by a smurfing landslide. I disliked math until I took Pre-Calc with him in 11th grade and Calculus with him in 12th grade, but after that it was easily my favorite subject, and Calculus I was probably my favorite class I've taken in high school or college to date. He just made everything so clear and made sure you understood it, so that by the time the AP test rolled around it was an absolute joke. I'm majoring in mathematics at this point and I'd say mostly due to him. He was also my varsity volleyball coach and easily the best coach I've had in any sport. I consider him an all-around mentor
