Doing right and good for society

by improving the accessibility, affordability, and sustainability of life science and healthcare.


Our mission

The accessibility, affordability, and sustainability of life science and health face significant challenges.

We must confront current policies, practices, and mindsets to bring about meaningful change and improve outcomes for all stakeholders.

With a clear vision of the future, we collaborate closely with our clients, striving towards a future where businesses serve as a force for good.


We firmly believe that a systemic change is necessary, prioritizing the value for society and the planet.


How do we help your organisation?

We are fully committed to delivering exceptional value by deploying a comprehensive range of services in life science and healthcare, firmly grounded in sound ethics.

Our primary focus is on driving systemic and transformative shifts in thinking and behaviour, with the ultimate goal of positively impacting both current and future generations.

We embrace courage and foster intense collaboration to make a difference in the healthcare system. We  believe that "good business" is supported best by:

Embracing a leadership role to drive problem-solving initiatives, collaborating with stakeholders throughout the value chain

Focusing on long-term sustainable effectiveness rather than to a short-term financial outcome

Taking an entrepreneurial approach

In a world in which change is inevitable, our challenge is how to cope with change on personal, organizational and systemic level. Especially in Healthcare, challenges are disproportional. How do we keep Healthcare accessible and affordable, while we also expect care and treatments to evolve, in order to extend our lives and improve our quality of life? Contributing to one of the most challenging issues of our modern society is a pleasure as well as a necessity.


A proven track-record in transforming businesses and people sustainably. I am keen on personal development and ownership during a change program, in close relationship with delivering results. I strongly belief that any change can only be embedded when personal change and team development are guided continuously.
My area of expertise is best described as business performance improvement in operations, with a strong focus on the change process and the transformation of the people involved.


Successful sustainable transitions require a partnership based on shared principles and values, a shared vision and shared goals!

It's about keeping healthcare accessible and affordable for which a well-organised logistics chain is of crucial importance. Ultimately, it is about ensuring patients to always have the necessary medication and medical devices at their disposal at the lowest possible cost. This requires thorough production processes, good stock management and, above all, an excellent logistics planning. That's my mission!


Supply Chain Management within pharma and medical devices is my expertise. I have experience in logistics planning, S&OP, transport management and in guiding the change needed for structural improvement. This is not only down to knowledge about processes and systems, but especially about being able to change together with the people within the organisation.


I’m inspired by using technological innovations to improve patients’ quality of life. I’m motivated to move clinical trials from R&D to the market. My role is to guide the people and teams working on this; helping them grow and develop to achieve more. Contributing to the quality of life together.
