Mrs. Mandy Martinez

I am the current Cheer Director and a U.S. History teacher at Johnson High School! I recently moved here from Colorado, where I was a Social Studies Teacher at STEM School Highlands Ranch, and the Cheer Director at ThunderRidge High School. I have been a coach since 2008, and in education since 2009. Looking forward to another year as a Johnson Jag!
