He was outstanding!!!!
Great teacher, great guy. Three years of classes and I had him as a quiz bowl coach we had a blast together.
bill spier taught me that science can be fun and interesting. among everyone i've come into contact with, he had the single greatest impact on my life
Best Teacher I ever Had. He knows how to get the best out of his students
A great teacher!! Gives great teachings and expects much out of his students, so keep a straight head and you will be just fine!!
His classes are so fun you can't help but learn in them. He's actually EFFECTIVE as a teacher and doesn't just stand in front of class and recite a lesson plan
Great teacher, wish I was back in HS with him instead of here at college!!
