Antoinette “Toni” St. Clair-Fish, FMCHC, NBC-HWC
I work with individuals and patients in healthcare practices who are doing all the right things—yet still struggling to make those efforts sustainable in real life.
Like many of the people I now support, I’ve experienced what it feels like to lose momentum, clarity, and connection to my own well-being. That experience didn’t just shape my path—it transformed the way I approach coaching.
Today, my work is not about offering more information. It’s about structured, compassionate implementation.
Whether I’m guiding individuals through sustainable habit change or collaborating with healthcare teams to support their patients, my role is to help translate well-designed plans into real, lived results.
My “superpower” lies in helping people move from knowing to doing consistently by bringing clarity to complexity, creating personalized and practical strategies, and offering the kind of support that makes lasting change possible.
Grounded in functional medicine principles and behavior change science, my work bridges the gap between clinical recommendations and real-life implementation.
I believe true healing goes beyond symptom relief. It involves shifting beliefs, integrating simple (though not always easy) practices, and reconnecting with your true self—by identifying and leaning into your innate strengths.
Science-backed. Strengths-based. Designed for sustainable healing and whole-person wellness.
ABOUT ME
My Training & Perspective
My work is grounded in both lived experience and formal training in lifestyle and functional medicine.
I am a National Board-Certified Health & Wellness Coach (NBC-HWC) and a Functional Medicine Certified Health Coach (FMCHC), trained through a partnership with the Institute for Functional Medicine—a leader in systems-based, root-cause healthcare.
This training allows me to translate complex clinical recommendations into clear, personalized, and sustainable action—bridging the gap between what you’re told to do and what actually works in real life.
My background in Nutritional Endocrinology as both an educator and coach further shapes my Food As Medicine approach—helping you better understand how nutrition supports hormonal balance, energy, and overall well-being in a way that feels practical and sustainable.
I also integrate Positive Intelligence® and strengths-based coaching to support not just behavior change, but the mindset and patterns that shape long-term success—both in your health and in your life
Simple, sustainable practices that support me—in real life.
This work isn’t just something I teach—it’s how I live.
Over time, I’ve learned that sustainable health isn’t about doing more—it’s about doing what truly supports you.
For me, that looks like a daily yoga practice to stay grounded and connected, and walking at least a couple of miles each day—not because I have to, but because it supports me mentally, emotionally, physically, and spiritually.
I used to be a dedicated long-distance runner, but like many of my clients, I’ve learned how to adapt my approach over time—choosing what works best for me in this season of life.
I also love rebounding—it’s one of my favorite ways to support cardiovascular health in a short amount of time, and it reminds me that movement can be both effective and enjoyable.
At the core of it all, my approach to food is rooted in a plant-forward, whole-food philosophy—simple, nourishing, and sustainable.
Because real change isn’t about perfection—
it’s about alignment.
