Our Team
Marietta Bertleff (Arts & Medical Director)
Mariëtta Bertleff (BIG registration: 29024262101)is a plastic surgeon and co-founder of Oraphi Health. In her work, she has spent many years within the conventional medical circuit, with all the precision and possibilities that entails. At the same time, she noticed that not all changes in the body can be easily explained within existing care pathways.
This search for coherence is both professionally and personally significant for her. As a patient, she encountered the same questions: what happens in your body when symptoms are unclear yet definitely present?


Danielle Krijtenburg (Coach)
So that you make choices that are in line with who you are.
Time to gain insight into your blind spots and your patterns, so that you can change your behaviour. Awareness is the first step!

Robert den Boer (Regional Trainer)
Our mission is to support as many people and companies as possible with accessible and qualitative guidance in the field of sport and health. We do this by matching the right coach or personal trainer to the desired person, whether that is at home for individuals or tailored within organisations and companies.
We do not believe in isolated vitality initiatives, but rather in structurally integrating movement and health into the workweek. Only in this way can sustainable results and lasting impact be achieved.

We work with a network of carefully selected, local personal trainers and health coaches, each bringing their own expertise. By connecting these specialisms, we create a strong and flexible platform that responds to a variety of support requests.
Our vision is to further expand this network and gradually roll out Regional Trainer nationwide. By connecting strong local professionals to us, we aim to make high-quality guidance accessible in every region.
Mathijs Rumke (Coach)
Matthijs Rumke has been working in and around healthcare for over 30 years, of which the last 16 years as a coach and trainer in the field of behaviour and communication.
Within the collaboration with Oraphi, he focuses on a specific phase in the process: the moment when a clear plan is in place, but the application in daily life does not yet come naturally.
In practice, it turns out that this is often where the challenge lies. Not because people do not want to, but because knowing and doing are two different things.
His approach is down-to-earth and practical. No new methods or complicated models, but working from a fixed and proven structure:
• understanding how behaviour and recovery work
• clarifying what this means in one's own situation
• making concrete choices and maintaining this in daily life
Matthijs works one-on-one and in small groups, as this is where space arises for real reflection and application. His role is not to take over or direct, but to support people and organisations in making their own translation to what works, in their own context.
