Her reputation for precision, warmth, and natural results has earned her a loyal following that stretches beyond city limits.

Outside of the treatment room, Julie is a proud mom of two and the embodiment of her favorite motto: “work hard/play hard.” That energy infuses every part of A Better You, making the medspa not only a place of transformation but a reflection of the high standards and personal care Julie brings to everything she does.
OUR CLIENTS STORIES
"BEST HANDS DOWN"
Julie was amazing and the Botox was on point. I have received Botox from several different providers and she is by far the best. She knows where to inject yo give you exactly what you are looking for and trying to achieve. Best hands down"
"WARM & KNOWLEDGEABLE"
I've never been to a Medspa before and I didn't really know what to expect but A Better You Medspa has created such a calm, beautiful environment- warm and knowledgeable. I love the B-12 shots! They've given me so much energy-especially in the mornings. I don't even drink coffee anymore. I would recommend this Medspa to anyone in Knoxville.

"ABSOLUTELY AMAZING"
Kirstie is absolutely amazing! I have religiously went to her the last 5 years and couldn’t imagine ever going to another lash artist! Her retention and technique are unmatched by other lash artists in Knoxville. Every time I’ve ever been in her chair, she has made me feel so comfortable and listened to what I want my lashes to look like and made it happen. 10/10 every time with her.
