A Little About Me

Hello! My name is Sierra Clark. I am a math teacher and coach living in Owasso, Oklahoma with my husband. We love to go camping, spend time at lakes, attend sporting events and do anything and everything possible with our pups! I also enjoy running, going to the gym, reading and spending time with friends and family. 

Teaching has been a passion of mine for as long as I can remember. I specifically became a math teacher with a goal of showing students that they can be good at math even if they have not had a good experience in the past. I feel so fortunate I get to do this at one of the best high schools in the Tulsa area! 

In addition to teaching, I coach cross country, girls wrestling and track. Bonding with students outside of the classroom is a high priority for me as I have seen how it directly impacts their attitude in the classroom.
