The fundament of everything is relationships. When they work – everything works. When they are out of sync, then issues arise in work, in family and in ourselves.

As a systemic relationship coach I make relationships simple work better – in business and privately.

I inspire, connect and support leaders to be their whole, courageous and authentic

to create human-first organisations that bring people together and deliver sustainable results. morning In business I support leaders and teams deliver their agenda by revealing and working with the hidden dynamics present through coaching, facilitation and consulting.

I support and guide organisations leadership who are looking to create change within the organisation; who want to create a culture of humanity, adaptability and business success.

In my private practice, I work with relationships that are out of balance and support them to find balance, flow and harmony.

People describe me a strategic thinker, results driven, someone who can connect the dots and navigate complexity. A storyteller who can articulate what is happening (visible and invisible) within the business; relational, adaptive, connected and an activator.

I love to support people and business and their journeys of discovery and change.

I have spent 12 years in executive coaching, leadership development and change management  and still every day brings something new. I have the honour of working with individuals who are at the tops of their game yet still looking to go further

who recognise that that means going deeper.
I want people to use the whole gamut of their emotions in their decision making, ambitions and growth.

I have over 30 years of corporate career experience that provides the base for being seasoned sparring partner for board members and executives. Add to that, 23 years of marriage and bringing two independent children into the world – I feel like there is no challenge I cannot take on and overcome 🙂

My clients can be found in both profit and not for profit sectors, local as well internationally.

I’m an ‘undercurrent specialist’ – revealing and working with the dynamics that exist in any team and organisation.

I have spent 25+ years working with change in organisations. From setting up and reorganising internal communications to developing and planning change programmes. Sometimes as a consultant: walking in and out when needed. Guiding and coaching MT’s, teams

individuals. Sometimes with my feet in the clay as an interim manager, working on a day-to-day basis as part of a change team.

The last 10 years I have found my passion in systemic work, being trained as family and organisational constellator. I am also trained in the Transactional Analysis, the Enneagram and Deep Democracy tooling.

I’m a huge fan of Yuval Harari, an Israeli historian and futurologist. Whenever I can, I share and use his insights for the future with my clients. So far, they love it.

I live in Amsterdam IJburg together with my partner and teenage son and daughter. At least once a week one of us prepares a tasty and healthy meal from one of my Ottolenghi cooking books.

I am absolutely fascinated by the psychology of change within organisations. When the most obvious does not work, I get involved.

For the last 25 years I have been working with individual coaching, leadership and team development; chairmanship & process guidance at meetings; designing development paths, conferences and meetings; systemic advice and organization constellations.

I mostly guide (international)

and individuals in their development, all levels. I am particularly fascinated by the dynamics within and between people. Mostly when the most obvious does not work and when it comes to the human side of change. I use organizational science, psychological and anthropological perspectives such as the Systems Approach, organization and family Constellations, the Gestalt Approach, Group Relations, Transactional Analysis, Systemic Analysis, and Insights Discovery. I use these approaches creatively and unconventionally in co-creation with the client. I am creative, clear and in a safe way confrontational towards measurable results.

I’m passionate about human potential and i’m driven by change.

My life has always been subject to change, be it by choice, or because life presented me with changes. Due to my life experiences I developed a great interest in human behaviour and potential. I like to go to the core of being human – ones

autonomy and identity. This has become a great driver in everything I do. Only from the core and with trust we can grow, change and transform.

To get to the core I use different elements from the attachment theory and Identity Oriented Psychotrauma therapy. From a systematic approach I support clients in their personal, leadership and cultural transformation.

Once we know who we are we can move to what we want and reach our full potential.

For more than 10 years I have supported international organisations, teams and individuals in their full capacity for growth and transformation. As a coach and facilitator of transformation I bring transformation journeys to life.

I share my life with Tim and I enjoy practicing yoga, running and above all dancing tango.

Until my early forties my actions were driven by what I thought others expected of me. I only discovered my inner needs and strengths in a transformation triggered by a personal crisis. Ever since, these inner drives have been leading how I live which, in turn, have made me a more confident and happy person.

Professionals, leaders

face many complex challenges in the areas of finance, risk & governance, and strategy & leadership. My passion is to support organisations unravel these challenges. In that I support professionals and leaders to find their inner strengths and become more creative, have a greater impact and be just happier in what they do.

I’ve travelled the world, living in Oman, London, Moscow and Manilla. I’ve enjoyed the diversity of moving from commercial roles to risk management and being a Chief Auditor at ING.

In parallel I developed from being a finance specialist into a manager and leader focussing on organisational and cultural change and transformation. In that I shifted from influencing primarily through the rational and content to influencing through human behaviour. Next to work I have always been involved in matters important to society like being a city council member. In this phase of my life I choose to help people and organisations to unleash their inner strengths in the openness of a new organisation.

I share my life with Lonneke and we enjoy being with people, for example, we love cooking and organising dinners, running, hiking and just being in nature.
