For years, many people have struggled with chronic pain, fatigue, weight loss resistance, and hormonal imbalances—bouncing between personal trainers, physiotherapists, and nutritionists, yet never finding lasting solutions. The truth? Most approaches only scratch the surface, treating symptoms instead of uncovering the root cause.
At ONE by Marie, we’re bridging the gap by combining the expertise of ONE Institute with the holistic powerhouse that is Instituut Marie. Together, we bring a 360-degree approach to health, performance, and well-being.

We believe that true transformation requires a fully integrated approach, where fitness, rehabilitation, and medical expertise come together under one roof. Whether you’ve been battling injuries, metabolic health issues, or simply feel like your body isn’t responding the way it should, we’re here to help you find real answers and lasting solutions.
The ONE by Marie Difference
Most health and fitness programs take a one-size-fits-all approach. At ONE by Marie, we take a science-backed, highly personalized route instead.
We’ve built a team of expert personal trainers, chiropractors, osteopaths, psychologists, metabolic health specialists, and dentists—all working together to connect the dots between movement, metabolism, and overall well-being.
Using cutting-edge tools like the PNOE Metabolic Analyzer, we identify the hidden reasons behind:
✅ Chronic pain (lower back, shoulder, headaches)
✅ Unexplained fatigue & low energy levels
✅ Stubborn body fat & hormonal imbalances
✅ PMS, menopause, and post-natal challenges
✅ Digestive issues & food intolerances
At ONE by Marie, you don’t have to guess anymore. We offer a complete roadmap designed specifically for you—helping you move better, feel stronger, and finally take control of your health.
