Dr. Maria Aguirre MD, FAAP

Chief of Staff

I am Dr Maria Aguirre, proud daughter of Barbara Barrera Aguirre, a very dedicated nurse and advocate for her patients. My father, Ben Rosales Aguirre, was a great believer in people with strong work ethics. He was a devoted activist for laborers who deserve the benefits of the American Dream.
I was raised in a modest home in West Texas and attended primary, middle, and high school there.  I loved sports and played in all available to me, but of course enjoyed my academics as well. I was always on the Honor Roll and voted most likely to succeed.
Relocating to San Antonio, I finished high school as Valedictorian and went on to complete a bachelor’s degree at Our Lady of the Lake University in Biology and Chemistry. I ventured out to the East Coast to attend the University of Pennsylvania School of Medicine to realize mi sueño, my dream, of becoming a physician.
Desiring to return to my home to care for a wonderful community of loving families, I chose to come to University of Texas Health Science Center to care for beautiful babies, children, and teens.
I finished my Pediatric Residency at the University of Texas Health Science Center, San Antonio (UTHSC SA). Looking back, I’m realizing I have practiced pediatrics on the West Side of San Antonio for over 32 years! My practice is both clinic and hospital based.  I have four wonderful sons whom I love dearly.
Why my love for Pediatrics?  Bright smiles, bright futures, love of life and vulnerability necessitating more love, more care and dedication. It makes my life blossom every year!
