Nobody ends up on this team by accident.
Everyone here chose this field on purpose, and they learn from a founder who teaches laser technology to other practices. They keep learning, and nobody is ever pushed to sell you anything.
William Espinoza, RN
Nurse Injector
Will is a registered nurse and the practice's nurse injector.
The first visit is a conversation and an assessment, and the plan comes out of that, whichever provider you sit down with.
Start with what’s on your mind.
You are not supposed to know what you need. Tap anything that has been on your mind. We will show what people usually ask about for it, and keep a list you can bring to your consultation.
Face
Skin
Body
Hair and ink
Wellness
You are not supposed to know what you need.
Forty tabs later everything sounds the same. Figuring out what fits you is our job, not yours. Here is how a first visit goes.
A conversation
The first visit is a conversation, not an exam. It is complimentary, in person or on Zoom. If all you do is talk, that counts.
The assessment
This is the skill. We look at your skin, hear what has been on your mind, and go over your history before anyone mentions a device.
An honest plan
What fits, in what order, and what it costs. Sometimes it is the less expensive option. Sometimes the honest answer is nothing yet.
Treatment, and after
We do not leave you hanging. The prep, the treatment, and everything that comes after.
Trained by the person who trains other practices.
Marissa Martinez-Thiele founded the practice, and her other job is teaching. She is a laser trainer and educator for Learn Aesthetics, and an international clinical laser trainer for Cutera. Other practices learn this technology from her.
Her own team learns it from her first. When a new machine comes in, people fight to be in the training room. The technique gets drilled for months, down to the small adjustments you would never notice.
10,000+procedures. Then she stopped counting.

Fraxel Dual
Fractional laser resurfacing for tone and texture.

“You already look like you. My job is you on your best day.”
Marissa Martinez-Thiele, founderNobody here is selling.
Our goal is not to sell you anything you don’t need. Sometimes the honest plan is the less expensive one, or nothing yet.
Natural, on purpose.
We start light and add later. The goal is you, rested and bright, never someone new.
Prices, out in the open.
Every treatment page shows starting prices, and the first visit is complimentary. Your exact plan and price come from the assessment.
Nervous is normal.
The first visit is a conversation, not an exam. As Marissa tells nervous patients: I promise you’re in good hands.
Real patients. Their own faces.
Drag the line to compare. These are people the team here has treated, and none of these photos are stock.




Results vary from person to person. A consultation is the only way to know what fits you.
