I Graduated from the University of Idaho in 1994 with credentials in Secondary Physics and Mathematics. After teaching almost every possible subject the public schools have to offer-- including but not limited to--Physics, Chemistry, Astronomy, Anatomy, Earth Science, Life Science, Algebra, Geometry, Trigonometry, Calculus, AND a few years as a full time long term substitute teacher, I bumped myself upstairs to the University level, receiving my Masters in Adult Education in 2003. I have since taught developemental mathematics for students ages 18-80 at Idaho State University, Boise State University, and Eastern Idaho Technical College, including GED and ESL students.
