Denise Thornton

My 20-year (and counting) journey as a mathematics teacher and leader has been a “trial by fire.” I learned to survive working with high school teenagers, middle schoolers, fellow teachers, and school administrators through resiliency and a commitment to learn and find the resources needed to navigate life as an educator.

My career has been guided by the strong belief that each child—no matter his or her background—should have access to high-quality mathematics curriculum and instruction and should benefit from the educational materials, professional learning, leadership, and policies necessary to succeed in postsecondary study.

I taught high school in New Orleans and learned how to survive day to day by working with diverse sets of resilient educators, administrators, and students. I learned that regardless of teaching expertise, we can always make students feel like their learning and future trajectories are a priority. As a doctoral student at The University of Texas at Austin, I’m grateful to have the opportunity to teach freshman calculus students with my advisor, Professor Uri Treisman.

It’s been both a challenge and an incredible joy to discover the right combination of words to share an idea. Dedicating my career to exploring creativity has led me to meaningful work that empowers others. Working at the Charles A. Dana Center is where my passion for purpose and creativity meet.

My passion for education began in sixth grade through my experiences with a caring, passionate teacher, Mrs. Ivie. After high school, I attended Eastfield Community College, in Mesquite, Texas. As a first-generation college student with limited financial resources and family support, I was embraced by Eastfield’s faculty and staff, who encouraged, supported, and pushed me to pursue my educational goals.
