Dr. Andrea Vargas-Garcia was born in the Bronx, New York, on National Dentist Day. From the age of 3, she has dreamt of becoming a dentist. Dr. Vargas received her Doctor of Dentistry from the Universidad Iberoamericana, then in 2018, she received her Doctor of Dental Surgery degree from UCLA and went on to earn her certificate in Pediatric Dentistry at the University of Puerto Rico. Dr. Vargas has devoted time to 4 mission trips that have taken her all over the world.  She’s aided the communities of Cotui, Dominican Republic; Kunming, China; Santa Apolonia, Guatemala; and Vieques, Puerto Rico.

Dr. Vargas finds that the most rewarding part of pediatric dentistry is having the ability to make a positive impact in the lives of patients by contributing to their overall health through their oral health. She is personally committed to never stop seeking the greater good and well-being of her patients. She believes that all patients deserve the highest standard of care.

During her time away from the practice, she enjoys reading, hiking, and, above all else, spending time with her family.

Dr. Garza earned his bachelor’s degree from the University of Texas at Austin (Hook ’em!) before completing his Doctor of Dental Surgery degree at the University of Texas Health Science Center – San Antonio in 2020.

Following dental school, Dr. Garza practiced as a general dentist in a pediatric-focused office in the Rio Grande Valley. It was there that he discovered his true calling: creating positive and impactful dental experiences for children. This passion led him to specialize in pediatric dentistry, completing his residency at UTHealth Houston.

Now, Dr. Garza is thrilled to be back in the Rio Grande Valley, providing specialized care to the children and families of our community. He is dedicated to creating a comfortable and fun environment where every child can build a foundation for a lifetime of healthy smiles.

Outside of the office, Dr. Garza enjoys spending quality time with his friends and family and is always on the lookout for the next great coffee shop.
