Katie Sevier
Hi, I am Katie Sevier, owner of Smooth Aesthetics. I am a nurse with a master's degree in anesthesia (CRNA). I have been getting aesthetic treatments since my late 20s and take pride in maintaining a natural, youthful look.
I loved the confidence aesthetics gave me so much that I decided to help give people that same level of satisfaction and self love! I trained with one of the best injectors in the country at Beautiphi Institute. With a strong focus on anatomy, physiology, and natural results, I have trained tirelessly so I can expertly inject every single one of my clients.
I am extremely passionate about my work and about the results of every single one of my clients. My focus is always on each individual client's needs, extreme attention to detail, and to naturally enhance your beauty that is already there. I love what I do and I can't wait to meet you!
