Mrs. Allison Tollefson

Welcome to PSHS! My name is Allison Tollefson, and I teach ESL Geometry, Math Models, and Algebra 2. I started teaching here in Spring 2021. I am a Plano Senior High graduate, and I feel honored to be back here as a member of the faculty. I found my dream job doing my two favorite things: teaching math and helping students develop multilingual communication and literacy skills. On a personal note, I am married and have a 2-year-old son, William, as well as a dog and a cat.
