About VIVE Aesthetics
Healthy skin first. Subtle everything else.
A regenerative approach to aging in Saginaw, MI: we build skin quality first, from a provider who'd rather under-do it than over-do it.
If this sounds like you
Oh thank goodness, she gets it.
If you've ever caught your skin in the car mirror and thought "when did that happen?", you're in the right place.
Maybe you've bought every serum on the shelf and still don't know what's working. Maybe you've had a facial that promised glass skin and delivered nothing. Or maybe you've been "thinking about" Botox or lip filler for three years and keep talking yourself out of booking.
I don't think you should have to choose between looking fresh and looking like yourself. And I don't think you should have to walk into a med spa feeling like you're about to be upsold.
At VIVE, our mission is to walk beside you and help you reconnect with the version of yourself you may have put on hold while caring for everyone else.
My superpower
Results so subtle, people just think you took a vacation.
I specialize in regenerative aesthetics: building skin quality with Sculptra®, PRF and medical-grade skin treatments, balanced with full-face Botox. We fix skin, not fill faces. (Lips welcome.)
I love a good glow-up. I just refuse to give you lips that walk into the room before you do.
What I care about behind the needle
Three values, in real life terms.
Your face, not a trend.
I'm not copying the lip shape that's all over Instagram this month. Your anatomy, your expressions, and how you want to look in ten years all shape your plan.
You'll always know what's happening.
Which product, how many units, where it's going, and why. I never want you lying there wondering what's in that syringe.
Safety is the floor.
FDA-approved products from authorized distributors, a team certified in every treatment we offer (and recertified every year), sterile technique, and an emergency protocol I hope we never need.

Why I work this way
The story behind the subtle.
I've been a nurse since 2010 and a nurse practitioner since 2018. Before founding VIVE, I worked in the NICU, neuro step-down, endoscopy, pulmonary, pain management and nursing education.
Every one of those shaped how I treat you today. The NICU taught me precision and a gentle hand. Pain management taught me how much comfort matters. Teaching nurses taught me to explain everything clearly, so you never wonder what's happening. And all of it taught me that trust is everything, especially when someone lets you near their face.
When I moved into injectables, I kept meeting women who had been overfilled, overcharged, or rushed through appointments that never felt like a conversation. A lot of them had sworn off treatment altogether.
So I got obsessed with doing it differently. I made sure our whole team is certified, both online and in person, in every single treatment we offer, with retraining and recertification every year. I studied facial anatomy far beyond the basics and built my whole process around starting conservative and adjusting together.
There's no single certificate that makes someone a great aesthetic nurse practitioner. For me, it's a collection of experience and a drive to always ask why.
These days my goal isn't the most dramatic before-and-after. It's that you still love your face six months from now, and so does everyone who sees it.
