Why TSAS? I believe every student is capable of succeeding in mathematics. It is my goal to encourage students in their ability and hopefully help them to find a love of mathematics.
Interesting Fact I have two beautiful children that both have blonde hair and blue eyes.

Pre-Calculus takes the concepts and skills from Algebra II and extends both depth and application. Calculus is the mathematical study of continuous change. This class will provide an introduction to some foundational Calculus concepts and should prepare you for any College Algebra course as well to go on into Calculus.



Trigonometry is a branch of mathematics that studies relationships involving lengths and angles of triangles. Trig students are ready to learn: trigonometric functions, trigonometric graphs and identities, advanced forms of geometry, and real world applications.
