Irene Mattison is more than just a crossing guard with the Frisco Independent School District.
Every morning, she dances as she welcomes teachers and students to school, and puts a smile on everyone's face while doing so. She says, "I can exercise. I can dance. I just can’t sit still that long while keeping my people safe. That’s why I do it, t’s not a plan. I just do it. I can’t explain it."
