What Clients Are Saying

I'm so glad that I found Wendy for my Botox! I won't go to anyone else now. She is sweet and so thorough, did exactly what I wanted. It's nice to work with someone who is so experienced and knowledgeable. I highly recommend Wendy to anyone in need of Botox or facial treatments.

From the very first phone call, Wendy’s warm and friendly vibe totally won me over….it’s the reason I booked my appointment! She was super sweet and really knew her stuff when it came to all the different products, which made me feel so much more relaxed about everything. I also really appreciated how she took a more conservative approach with Botox. She clearly knows how to keep things looking natural and fresh, not overdone or fake.
I’m 100% coming back, and I’ll definitely be sending friends, family, and coworkers her way!

— Ally Lobo, google

I’ve been seeing Wendy for my aesthetic upkeep treatments for the past two years, and I couldn’t be happier. She’s incredibly knowledgeable, professional, and always makes me feel comfortable and confident. Her approach is personalized and never pushy, and her pricing is very reasonable. I truly trust her expertise and always leave feeling refreshed. Wendy is simply the best!
