Meet Dr. Ada Cuellar

Growing up in Weslaco, Texas, Dr. Ada Cuellar was shaped by her upbringing in the Rio Grande Valley and a deep commitment to her family, her community, and now her patients. The daughter of an electrician and a homemaker, Ada grew up in a bilingual household that valued hard work and perseverance. Her parents invested in books and taught her to love learning. She excelled in school, driven by a determination to build a better life for her family and others like them.

Ada graduated from UT Pan-American and earned her medical degree from UT Medical Branch in Galveston. She completed her residency in emergency medicine at Temple University Hospital in Philadelphia and returned home to serve her community as an ER doctor, where she has witnessed firsthand the consequences of underinvestment in healthcare and education.

In her pursuit of fairness and equality for Texas at every rung of the economic ladder, Ada was inspired to seek a law degree while continuing to help her community as a practicing doctor. She’s passionate about using her knowledge of both medicine and the law to tackle the systemic failures harming South Texas families – from unaffordable healthcare, to a broken education system, to an economy that limits opportunity for working people.

She understands how unaffordable deductibles, poor health education, and inaccessible care leave even insured families terrified to seek help. She’s seen patients avoid treatment due to cost - some leaving ERs in dangerous conditions – while politicians like Monica De La Cruz offer little more than MAGA soundbites.

As a single mother, Ada’s raising her daughter to believe in service, compassion, and resilience. And that’s why she’s running for Congress. Dr. Cuellar knows South Texans deserve a representative who understands their lives, shares their struggles, and has the experience and ideas to actually deliver results.

She’s not a career politician. She’s a working mom, a doctor, a law student, and an independent thinker ready to fight for a better future.

Her campaign is about building a healthier, smarter, freer future where opportunity is real, healthcare is accessible, education opens doors, and no one is left behind.
