Mrs. Shawna O'Brien

Meet Mrs. O'Brien!

This is my third year as the reading teacher.  I have been with SLPS for nine years and teaching for 13 years.  I completed my studies at the  University of Missouri-St. Louis.  I enjoy gardening, reading, and spending time with family and friends. I also have a passion for sports and the concept of being on a team.  (Lets Go Blues and Bears!!)   I am so excited to have the opportunity to serve the students here at Mason!  You can contact me at  My planning time is 9:05-9:55 and I am available during that timeframe with the exception of Thursdays.
