Collaborating
For organizations that feel things need to change — and are ready to take that step together.
Organizational and team development often requires more than one area of expertise. That’s why I enjoy collaborating with a select group of experienced professionals on larger or more complex projects. People with whom I not only share sharp insights but also common values: clarity, commitment, simplicity, and sustainable impact. .
What connects us is a shared vision: the belief that organizations need a fundamentally different approach. The current ways of working, thinking, and acting no longer meet the challenges ahead. We believe it’s time for new perspectives — making space for humanity, ownership, and systemic awareness.
Our collaboration is built on trust, equality, and a deep sense of collective strength. We complement each other, challenge each other, and amplify each other’s work. Depending on the question, context, and size of the project, we create a tailored approach together. Sometimes I work with one of them, sometimes with several.
What unites us is a systemic view — and a down-to-earth, human approach to making a real difference.
Meet my collaboration partners:
Darcy Dautzenberg
heelopstellen.nl • Boven en Beneden de Rivieren
Darcy is a systemic coach, organizational consultant, and co-founder of Boven en Beneden de Rivieren, where we translate systemic insights into practical tools for leaders and teams. Her strength lies in working with what’s unspoken — undercurrents, loyalties, and invisible rules.
She brings calmness, clarity, and humor, and specializes in leadership development, team dynamics, and organizational constellations.

Melanie Sarlemijn
Helder helps further – BoeM Constellations and Development
Melanie is sharp, quick, and lovingly keeps you on track. She has a down-to-earth perspective, a big heart, and extensive experience guiding people and teams that feel stuck or want to move forward. Together we organize constellation mornings under the name BoeM Constellations and Development.
Melanie excels in team development and, with her knowledge of Deep Democracy, creates space for all voices in the room — especially those of the minority. She operates at the intersection of coaching, constellations, and personal leadership, and instinctively senses where the core issue lies.
She asks the necessary questions, brings clarity, and gets things moving.

Monique Tuinbeek
Renaissance Consulting
Monique is an experienced coach and facilitator working at the intersection of systems, behavior, and communication. She combines an analytical mind with a warm presence and quickly reveals patterns within groups.
Working with Monique means depth and direction, with attention to what’s happening on multiple levels. She has extensive experience in team development and organizational challenges where tension and friction arise.
Do you have an issue around leadership, team dynamics or organizational development where you feel: this requires multiple perspectives and strengths? Then I would be happy to think with you about an appropriate composition.
