Ms. Mary Rose O'Shea » Welcome


Greetings! My name is Mary Rose O'Shea, and I am an English language arts teacher here at Mather High School. Mather has been my professional home for nearly 20 years, and I am consistently grateful for the opportunity to work with the amazing young people who walk through our doors each day, year after year. 
Currently, I teach English III for juniors and English AP Literature & Composition for seniors. I also have a release period to serve as an instructional coach. Outside of the classroom, I coach Mather's Academic Decathlon team and co-facilitate the Mather Literacy Center with Mrs. Belmonte.
