I Have finally found my aesthetics person! MJ is amazing. I’ve never had someone explain so much and in detail. I feel like she cares and definitely has a great hand. No bruising or painful.

I cannot love MJ more!! I feel so safe and comfortable in her care. She’s constantly concerned with making you feel beautiful while being sure you don’t ever do too much or too little. She’s got great touch and is always learning about the newest and best treatments in the industry. So thankful for her and for the whole fabulous crew at Tonik!! Thank you for taking care of me

MJ and the entire Tonik team have been absolutely incredible! They’ve helped me identify exactly what was missing for me to truly feel my best and have supported me in getting my thyroid and gut health back into balance. They’re so attentive and thorough, even with me being out of state, and I’ve felt so cared for throughout the entire process. I’m beyond grateful I found them! ❤️

went in today for my Dysport treatment and the entire experience was fantastic from start to finish. MJ is literally the cutest, and I mean that in every way — from her sweet, welcoming personality to the genuine care she puts into her work. She took the time to understand exactly what I wanted and made me feel completely comfortable throughout. Her technique was precise and gentle, and I finally feel like I’ve found my go-to nurse!

She took the time to really listen to my concerns and offered thoughtful, personalized recommendations without ever making me feel rushed. Her professionalism, knowledge, and genuine care made for such a positive experience. Thank you!"

You just don’t get care like this at a gp appointment. This is hyper focused, incredibly personal, and wildly educational. You learn things about your unique needs that have been shrouded in mystery and vague ideas your whole life and it’s super empowering to be given that intel so freely and compassionately. MJ is the best at what she does and everyone in the office is super sweet, warm, and professional. If you’re looking for functional care this is your place!

My virtual visit with MJ was everything I was hoping for and more! From the moment I scheduled my appointment, her staff was incredibly kind, responsive, and supportive. They guided me through every step of the process, stayed in touch, answered all of my questions, and made sure I felt comfortable before my visit even began. During my appointment, I truly felt heard—especially because I can talk a lot!

I had my CO2 laser treatment at Toniik today and had such a great experience! MJ made me feel completely relaxed and comfortable throughout the entire process. I’m already super excited to see my results. I truly love this place — everyone that works here are incredibly sweet and welcoming. The space itself is trendy, cute. I always enjoy coming here and highly recommend Toniik! Love you MJ see you soon

I’m so grateful to have found Toniik! My best friend referred me and I will forever be a customer! I suffer from a rare condition called dystonia (cervical dystonia) which affects the muscles in my neck… I can’t control my neck movements, which can cause my neck to essentially have a mind of its own. I was in complete spasm before seeing MJ.

Had the absolute pleasure of visiting Toniik the other day and I am shocked to say the least. The level of cleanliness and professionalism that took place was beyond what I imagined. MJ and Eva took such amazing care of me and explained every single question I had. You could just tell they’re so knowledgeable about their services and they really want to have their clients happy. The spa was beautiful and sparkling. Every single staff member was kind and welcoming.

Not only do my fillers and Botox always look exactly how I want, but my skin looks healthier than it ever has. I never wanted to do micro-needling because of the downtime I always had to deal with but MJ suggested using the C02 Carboxy mask right after my session and some time under the red light and I couldn’t believe how little redness and puffiness there was after. I use the Carboxy mask once a week now and my skin feels so good after. So grateful for MJ and her staff!

True anti-aging starts in your biology. Most clinics treat what’s visible. We treat the cause, using real testing and measurable results.

Our six-step framework strengthens you from the inside out. By connecting your biology to how you feel, function, and look, we create a clear, measurable path to lasting results.
We begin with a full consultation, genetics, methylation and comprehensive lab testing to understand your baseline.
We improve your sleep, focus and mental clarity with targeted strategies designed to support cognitive health.
Your skin is your largest organ. We restore texture, tone and elastin before ever considering fillers.
We treat the deeper causes of ageing like bone loss and fat-pad decline using regenerative options such as human biologics, Renuva and precise filler placement.
We track hydration, metabolism, muscle mass, visceral fat and bone density because these numbers show how your body is ageing.
Your plan evolves with you. We monitor your progress and adjust your program so you stay strong, sharp and youthful over time.
