Meet Our Doctors in Richardson, TX

Dr. Estefany Montelongo

 ¡Hola! I am Dr. Estefany and very excited to be a part of the Thrive Dental & Orthodontics family. I was born in San Luis Potosi, Mexico, but moved to Texas when I was three years old.

I attended Texas Woman’s University and graduated from their Honors College with a bachelor’s degree in biology and chemistry minor

Immediately after, I began my dental journey at Texas A&M College of Dentistry where I received my Doctor of Dental Surgery degree. I’m the first college graduate and doctor in my family, which makes me feel even more proud of my achievements. 

As a dentist, I’m passionate about caring for my patients and educating them on the importance of oral health. I believe that prevention is key, and I’ll work with my patients to develop a personalized plan that meets their unique needs. I want to make sure that every patient leaves my office feeling happy, informed, and confident about their dental health. 


I am a major fan of live concerts; I love nothing more than feeling the energy of the crowd and getting lost in the music! I also love hosting at our lovely home in Rowlett where my husband and I also share a passion for cooking and creating new dishes. Lastly, I will always say yes to a night out with close friends to try new activities or restaurants.


Writing in my Five-Minute Journal each day. I am forced to write down what I can do to
