What do you like about teaching at TBCS?

I love teaching at TBCS because it is a great work environment! The students are very respectful and interested in learning, the faculty/staff are supportive and caring, and the parents are always spoiling us with treats! I love seeing the bond between students and teachers grow in the class and in extracurricular activities to the point where our students become like our own children. I couldn't imagine a better place to have completed my first year teaching and can't wait to return for the next school year!
