Sydni Sonnier

Welcome to Fourth Grade! I will be your homeroom, ELA, and social studies teacher. Mrs. Duehr will be your math and science teacher! I am a Frisco native, a Texas State University graduate, and currently a student just like you attending Texas Tech earning my Masters in Education- Wreck ‘Em! This is my 4th year teaching and my 3rd year being part of the Harrington family. I love the community and families that make Harrington so special! In my free time I love to be outdoors with family and friends, listen to live music, and watch my students play sports or show off their amazing talents. This year will be full of so many fun learning experiences! We will laugh, smile, and reach new goals together. I am looking forward to a great year and learning all about YOU!
