About us

Sickness Industry or Wellness Industry?

A conscious choice for empowered health. 

My Mission: Your Transformation 

Allow me to introduce myself. I am Marijke Engelbrecht, the founder of FlexHealth, a professional
health consultancy.


My mission is to facilitate and support you with the changes and choices necessary on your
transformation journey toward optimal health and personal power.

The Two Industries of Wellbeing

In our society, we have two kinds of industries concerning our wellbeing.

The Sickness Industry

The Sickness Industry places responsibility on the practitioner, not the client. It focuses on sickness and symptoms, not on the potential a person has to live a full life in optimal health. 

The Wellness Industry

The Wellness Industry inspires those interested in wellbeing. Here, people want to take full responsibility for their health. They are ready to be empowered and are looking for coaches,
consultants, and mentors to facilitate their self-empowerment journey.

Your Personal Roadmap to Optimal Health

I am able to think outside the box to help you create your own roadmap for physical and mental wellness. Your personalized toolbox will include:

  • Physical activities

  • Healthy eating & nutrition

  • Hydration

  • Sleep hygiene

  • Connection

  • Stillness

  • Science-based brainwork

This means a totally personalised program for your journey to optimal performance and health.

How We Work Together 

  1. Online PNIE Consultations

  • One-hour intake (We can order blood, stool, or urine tests if necessary).

  • One-hour explanation of your situation and a clear plan for recovery and performance. You will receive documentation afterwards.

  • Follow-up appointments (usually 3-4 half-hour sessions). The better you follow the advice, the fewer follow-ups you'll need.

2. Seven-Day PNIE–IL Plus Journey (France) 

This is a total immersion program synchronizing all your body's systems.

  • Extensive online intake beforehand to design your personal roadmap.

  • A week using hormetic stimuli to make your body and brain alert again, enabling optimal recovery and performance. We use: ○ Food, nutrition, hydration ○ Exercises, breathwork ○ Cold & heat exposure ○ Coaching, brainwork, mindfulness, yoga, breathwork ○ Infrared light, infrared sauna ○ Sleep hygiene

  • The Result: You will leave knowing how to easily maintain your results in daily life.

Your new motto will be: “Get fit, be fit, stay fit”

For Companies: The Science of Flow & Performance 

Personal and business success requires achieving the flow cycle—moving from struggle, throughrelease and recovery, into flow states.

 

In flow states, you will achieve incredible elevations:

  • Motivation & Productivity: +500%

  • Learning & Memory: +400%

  • Creativity & Innovation: +230%

  • Meaning & Purpose: +100%

  • Grift, Persistence, Collaboration, Ecological Awareness: Maximized

This leads to a growth mindset, task orientation, and employees who are fully present. The result?


More is achieved in less time with healthier, happier employees in a positive work environment

My program helps companies and teams achieve this optimal performance through preventive care, accelerated recovery, and immense cost savings.


I Walk the Path.

With You.
I walk this path myself.

I know the challenges because I have faced them too. I understand the roadblocks on your way to wellbeing.

It’s a lifelong journey, but believe me, it’s worth it. You will experience strength, flexibility, health,
and happiness.


That is my mission. I follow my heart and empower others with empathy. I am committed, inspiring, and passionate.

Biography – The Driving Force: Marijke Engelbrecht 

From physiotherapy (1986) to integrative medicine, to founding Centrum Engelbrecht and later FlexHealth Academy — Marijke has continuously integrated the latest scientific research into practice.

 

Her mission has always been clear:
Empower people with preventive and restorative tools to take control of their health.

 

Marijke completed her training at the Academy of Physiotherapy in 1986. Driven by a passion
for integrative health, she has never stopped learning, constantly integrating the latest scientific
advancements into her practice to provide the most current care possible.

In 1988, she founded her own practice, specializing in physiotherapy, acupuncture, and children's
sensomotor therapy. This practice evolved into Centrum Engelbrecht, offering a wide range of therapies
including integral manual therapy, BICOM bioresonance, orthomolecular medicine, nutritional advice,
kPNI, and the Intermittent Living®© concept.

 

 

In 2019, she channeled this extensive expertise into a new venture: FlexHealth. This corporate health
consultancy supports companies in enhancing employee wellbeing and effective business management
through the science of clinical Psycho-Neuro-Immunology

Marijke's mission has been clear from the start: to empower people by providing them with the preventive

and restorative tools to take control of their health. By understanding the root causes of disease and
leveraging the evolving science of kPNI, she offers a truly holistic approach to achieve this goal.

She is committed to making physical and mental health accessible to all and has extensive experience treating a wide range of conditions, including digestive complaints, hormonal imbalances, allergies, stress management, autoimmune diseases, and providing cancer support.
