Hi, my name is Diana S. Rangel and I work with students whose last name are A-Fa. I have worked for Harlandale ISD since the 1989-1990 school year. With the exception of two years, I have worked all my years here at McCollum. I love my job because I love my students and their famlies. I am honored that I have had the the opportunities to meet and get to know so many wonderful famlies.This year I was accepted into The Harlandale Hall of Fame, a recognition that I will hold dear for the rest of my life.
