Brielle is amazing! I’ve done lip filler, botox and Sculptra treatment with her & loving the results. The staff is very welcoming and the space is beautiful. My new favorite med spa.” Nicole Quintero | Google Review (May 2023)

“I went Thursday for my first injectables ever. Brielle was out of this world, extremely knowledgable in her craft, and it was apparent. Not to mention the pure passion she has for this. It DEF calmed my nerves. She was so sweet and accommodating to my absolutely giant fear of needles. So patient and understanding!” — Panda Herrera-Fling | Google Review (January 2022)

“I got lip filler with Brielle and she was incredible. I’m not from Texas so I was very hesitant about where I went but she is truly amazing. She took her time, explained everything in extreme detail, she reassured me, and made me feel very comfortable. I would recommend her to everyone!” — Alanna A. | Yelp Review (December 2021)
