Mrs. Katherine Stierly

Welcome! My name is Mrs. Stierly (STEER-lee), and I teach 6th grade English Language Arts and Math at Reiffton School!

Before I got married, my name was Miss Kocotas. You may see that name online and around my classroom! 


When you visit my classroom, you will see a lot of blue and green, and dozens of pictures of succulents! My students are part of my family, so I hope to display all of our family photos on the wall together. My favorite time of day is usually when we practice stamina reading after recess. We like to get super comfy and listen to the sounds of a crackling fire displayed on the whiteboard!


Family is incredibly important to me! My husband and I got married in August of 2020. We have a 6 year old Black Lab named Koda and a 3 year old Yellow Lab named Ivy. You'll see pictures of our little family around the classroom, as well as pictures of my parents and siblings.

I love to make Cricut projects, pick veggies from our garden, walk our pups, and shop at Target during my free time.


This is my second year in Exeter Township School District and my third year teaching sixth grade. I received my Bachelor of Arts degree in English Literature from West Chester University and my Master of Arts in Education from Rosemont College.
