More than skin deep

TONIIK was built around one belief: when beauty and health are treated together, results go further. MJ’s experience in both hospital critical care and private aesthetics allows her to treat the full picture — from acne and aging to energy loss and inflammation. The result? Treatments that look good and work hard behind the scenes.

Treatments that meet you where you are

From the outside, you’ll find injectable artistry, precision laser therapy, and regenerative skin treatments like PRP and biostimulators. Internally, we support metabolism, nutrient balance, and hormonal health using evidence-based methods. MJ’s concierge-style practice gives you access to both worlds, under one roof.

A full-body approach to aesthetic care

MJ believes that visible skin improvements begin beneath the surface. At TONIIK, every treatment is guided by science, safety, and your body's chemistry. From Botox and lasers to energy support and hormone optimization, each protocol is personalized to help you age smarter and feel stronger.

What makes TONIIK different

TONIIK isn’t a medspa. It’s not a wellness clinic. It’s both. Our patients come to us for expert facial balancing, precision injections, and innovative skin repair — but they stay because they feel supported, seen, and stronger after every session. MJ leads a hand-selected team and remains deeply involved in every care plan. Whether you're optimizing for beauty, balance, or both, TONIIK gives you the tools and treatments to keep showing up at your best — inside and out.

Where clinical expertise meets daily care

Every protocol at TONIIK is grounded in real medical experience — not just medspa trends. From dermal fillers to metabolism support, MJ applies a clinician’s lens to every decision. It’s not about doing more — it’s about doing what works, safely, and with intention.

"Where science and skin meet, you’ll find results you can feel — and see."

Don't Just Take Our Word For It

MJ is fantastic! I was nervous and had a lot of questions but she was incredibly kind and answered all of them. My face is so much more balanced now and she was committed to helping me achieve the natural looking results I wanted.
Anastasia S.
I had an amazing experience with MJ! I saw her work on one of her other clients via Instagram and knew I had to go to her for Biofiller-I wanted something natural for my under eyes and I liked the before/after I saw on one of her other clients.
Robin S.
MJ is amazing! I look 10-15 years younger! MJ and her staff are so friendly, and she does amazing work! I never realized the artistry in sculpting a person’s face, trying to create symmetry in an assymetrical face, all while making you look natural.
Dorothy S.
I’ve been a client of MJ for the past year and she has helped evolve my facial balancing as well as addressing skin aging and helping with my health goals. I have referred family and my closest friends to her knowing they are in the best hands.
Bethany F.
MJ is truly the best! Her expertise in providing the best advice for aesthetic procedures, health and skincare is unmatched. She takes the time to really understand your goals and concerns and then delivers with the most natural and perfect results.
Jazmine J.
MJ has recommended skin profucts for me, such as the Alpharet clearing serum and the skinbetter peel pads, and it has transformed my skin! My skin looks and feels amazing! She is the only person I trust with my face, even when it comes to injections/botox.

01

Backed by training. Refined by practice.

MJ’s experience in hospital medicine sharpened her instincts for safety and outcome-driven care. That same discipline carries through at TONIIK — where even the smallest tweak or dosage is made with clinical precision and aesthetic understanding.

02

A new kind of continuity in care

Our relationship doesn’t end at the appointment. With regular follow-ups, personalized adjustments, and direct support from MJ, every TONIIK plan evolves with your skin, body, and lifestyle over time.

Everything at TONIIK is built around a single belief: how you feel should match how you look. Whether it’s your first visit or your tenth, you’ll leave with more than a treatment — you’ll leave with clarity, confidence, and a clear path forward. Our patients come to us for change. They stay for care that feels grounded, personal, and effective. And that’s exactly how we designed it.
