“Your surgeon should uphold the highest standards…

“This should include qualifications and credentials that are your assurance of the finest care possible. The decision to change your body is important and deserves careful consideration with the guidance of an experienced, board-certified plastic surgeon.

“As a board-certified plastic surgeon, I have extensive education, training and knowledge of the body as a whole. This allows me to better understand what can be enhanced… and changed… to have a positive effect on my patient’s confidence, while it can also have an effect on the body’s well-being.

“The results of plastic surgery should be what my patient expects, while at the same time I am here to ensure realistic — and safe — outcomes. Together with my patient, we create a treatment plan that benefits my patient’s self-esteem, dreams and expectations.

“Personal attention is vital to my patient’s experience with me. A plastic surgeon should have empathy toward the patient’s wants and needs and provide an understanding of just how important a role confidence plays in one’s life.

“I am honored to help my patients achieve their dreams.”

Stephanie, Digital Marketing & Public Relations

Stephanie has been a Professional Makeup Artist at Gallas Plastic Surgery since 2010. However, with emerging emphasis on e-commerce, the Jane Iredale Makeup line is now mostly managed by their online presence and consumers value the convenience of shopping from home. As a result, we no longer carry makeup in our MedSpa, however, Stephanie continues to play a marketing role within our practice as she assists with social media, digital marketing, event planning, and community outreach.

As an active West Houston/Katy community member, Stephanie appreciates all of the best amenities that we have right at our doorstep, including renowned Plastic Surgeon, Dr. Gallas, and his state-of-the-art surgery center. A recent empty nester, she values spending quality time with her husband and 3 adult children whether it is at home in Houston or travelling the world.
