"When I think about my school days at Southwest, my fondest memories are of my algebra teacher, Mrs. Scott, who helped me to love numbers, Mrs. Segura, who help me understand the importance of writing and comprehending words, Mrs. Martinez, who loved to teach us Spanish, and the camaraderie of teammates which helped me to work with others toward a common goal."

"Its motivating to be part of The Southwest Education Foundation because I have been a life-long member of the Southwest district and I have had many family members that have and continue to attend SWISD. Which includes the first valedictorian, cousins, an uncle, siblings and my two children. In addition, my experiences as a university student, and my career in business showed me how important a good education is to being a well-rounded individual, one that will be better able to live and work in a diverse world. A good education helps our students build the confidence to make their place in the world."
