Find Important Information for the Solar Eclipse on Monday, August 21st, Below


Hi, I'm Mrs. Thomason!
This is my 18th year teaching mathematics, and my 5th year at CHS.
I am originally from Joplin, Missouri, where I graduated from Missouri Southern State University with a bachelors degree in secondary mathematics education. Shortly after I was married, I moved to Kennesaw, Georgia - a suburb of Atlanta - where we lived until my husband's job brought us to Collierville. We have two daughters, two dogs, and a turtle. 
I enjoy reading, jogging, crafting, walking with my dogs, and spending time with my family.
I LOVE teaching math at CHS. GO DRAGONS!
