Mr. Owsley is one of the best math teacher I have met in my life time. I have taken his Calculus BC class when I was a high school student. His class was interactive, inspiring and creative. He impacted me not only mathematically, but also as a human being in shape and form. I am currently a PhD student in math, and I am much in debt in the math education I received from Mr. Owsley. Despite of the fact that I have had a lot of math teachers on my way of doing mathematics, he remains one of my favorite, most inspiring, and motivating teacher. He explains problems with such a passion and clarity that I think his classes are very helpful to students working on the topic of calculus. I will very much recommend working with him through the way of calculus and other mathematical topics.
