8th grade parents: Please make sure that you are sending in both pieces of the green Shadow Day Form! I should have one piece before the day your child shadows and one the day after.


Hi! My name is Tiffani Coster and I am excited to be teaching your children this year! I started my career teaching in various schools in Harford County for 2 years as a Special Educator. In 2012, I was blessed to begin my time in the Archdiocese as a 3rd and 5th-grade teacher. This is my fourth year teaching at St. Joseph School and I couldn't be happier to be here.

I believe strongly in the value of a Catholic education. I began my own Catholic education right here at SJS in Kindergarten, with Mrs. James as my teacher! After graduation from 8th grade, I continued on to Institute of Notre Dame where I decided that single gendered education was perfect for me. I attended Notre Dame of Maryland University and graduated with a Masters of Arts in Teaching degree and dual certification in Elementary and Special Education.

Outside of school, I can be found hanging out with my puppy Penny and spending time with my family. I love going to concerts and watching the Orioles and the Ravens play. I also love reading and watching WWE and other professional wrestling.
