Kate Murphy
Sky Room (1st - 2nd)

Ms. Kate was once a student at the Circle School herself, which inspired her to become a teacher! She has spent over 14 years leading San Antonio area classrooms for Northside and Judson ISDs, including 9 years teaching 1st grade. She made the decision to leave the constraints of public schools (a sentiment to which many of our parents can relate) and was hoping to start her own microschool when she learned of our hiring opportunity. Ms. Kate is overjoyed to bring her educational journey full circle by returning to The Circle School and her wealth of experiences and passion for teaching will surely be great assets to our community.
