Simon Koolwijk

I became acquainted with Perspectivity through Han Rakels and Han Verhoeven. I like Perspectivity’s participatory approach in dealing with issues in complexity. The approach to ask open ended question and look every time at a situation with curiosity and openness is appealing in Perspectivity’s approach. Perspectivity is also working sector wide in society including NGOs, communities, businesses and governments in looking for sustainable solutions. People working with Perspectivity are committed, passionate and look at a holistic way on change and development.

I hope to contribute to Perspectivity’s approach by providing my expertise in participatory video and filmmaking. I am combining the art of filmmaking with community development. This approach fits to the approach of Perspectivity on how to deal with issues in complexity involving actors from different levels and contexts.

As a facilitator for organizations I want to give people time and space to learn. Ultimately, I wish for people to feel connected to the whole, while at the same time, feel as much personal freedom as an individual.

Of course, this beautiful aim will come accompanied with tensions, especially if people want to work together. These tensions can make issues (even more) complex. I believe, however, that if we can make room for our differences, it will results in a much stronger whole.

In order to facilitate this process, I find it important to use methods to tap into other layers of our knowledge, wisdom and creativity. Methods that are playful and positive and have a creative and / or transformative character. Such as Appreciative Inquiry, Theory U, Deep democracy process work and play coaching (theatre interventions). I also love using Lego Serious Play to engage everyone in the room and create energy!

These processes go beneath the surface and have a strong impact in terms of learning. My expertise lies in psychodrama and ‘participatory drama’. I love these methods for making complex issues visible and tangible, within a very safe learning space. They provide space to explore, experience and learn together and activate the understanding of everyone’s unique perspective, promoting cohesion and common ground.

My background is in Communication Science, directing for theater and film & personal development. So far, I enjoyed working as a facilitator and trainer for municipalities, schools, NGOs and companies – mostly on questions focussing on collaboration and change.

If your are looking for novel ways to help people discover new things about themselves or their group of when you need to address an organisational challenge (good or bad): call Anna. Anna is both innovative and practical as she does inspring work to bring new methods into contemporary (business) practice. Working with Anna is a delight.


Anne van Marwijk

Since 2014, I have been working at Perspectivity as a freelance consultant and facilitator. I really enjoy designing and facilitating multi-stakeholder processes and learning and evaluation trajectories.

My background is in anthropology and development studies. I have lived in different countries such as Mexico, the United Kingdom and Tanzania and am currently situated in Amsterdam.

From my background in anthropology and large fascination with languages, I am specially interested in connections and understanding between people.

In October 2014, I joined Perspectivity as an intern and then went on to become a young enterpriser within Perspectivity. Since 2016, I become an official partner in the collective (maatschap).

In my time at Perspectivity I co-developed research tool Sprockler to, through using the latest technological developments, make it easier to bring different perspectives together and find the connections between them. I train people in the approach and methodology behind the tool: how they can ask the right questions, how they can collect stories in a participatory manner, and start the conversation about the results for the story and data collection. In this way, I like to support people and organisations to use the tool to gain more insights into what is happening in their complex setting to make better decisions for the future.

Next to my work with Sprockler processes, I design and facilitate multi-stakeholder processes and learning and evaluation trajectories. Recent examples include the multi-stakeholder process around the shelter and guidance for undocumented people in the municipality of Amsterdam, the end review of  knowledge platform for inclusive development policies INCLUDE and the learning trajectory for the Young Leaders for Human Security programma of the Human Security Collective. 

For Perspectivity I also regularly produce visual reports of dialogue sessions or multiple day processes in the form of a website or newspaper. Examples of this can be found on our Publications page.

Elien Rogaar

For almost twenty years I have experience in facilitating organisational change trajectories and learning and development processes. As management trainer/consultant I worked with different organisations in the private sector in the Netherlands as well as with governments and civil society organisations in Africa, Eastern Europe, Asia and Central America.
Most of my work is on the field of organization culture, leadership, strategy development, performance management, team development and (large) group facilitation. I have an academic background in Organisational Psychology.

My approach is participatory, directed towards a shared ambition and focusing on common ground, collaboration and self-steering.

I worked at De Baak Management Centre, at MDF Training & Consultancy and at On-Lime Consultancy. In 2012 I co-founded Perspectivity Enterprise.

I am a certified change agent in Barrett Cultural Transformation Tools, Spiral Dynamics, Integral and Profile Dynamics, and Future Search. Often I apply the approach of Appreciative Inquiry and I am fascinated by the ideas of Theory U and systemic work.

And furthermore, I live a happy family life with Maarten and our two daughters, in the countryside near Amsterdam.

What other people say about Elien:

Elien is a thoroughly creative and inspired “facilitator of change”. She influences change processes tactfully and subtly while paying a great deal of care and attention to personal aspects. She approaches her consultancy work with integrity and has a good perspective on group dynamics. She also provides a comprehensive set of tools to help people and groups to understand their personality, motivations, beliefs and behaviours and to give them guidance.

Han Rakels

I am experienced in leading, managing and facilitating development processes all around the world.  I have worked with governments, businesses, universities and NGOs in Asia, Africa, the Middle-East, South America and Europe.

My academic background is in chemical engineering (PhD) and business administration, to which I added group dynamics, personal and organisational behaviour to make the cocktail complete.

I facilitate processes and conduct training in order to effect long-lasting change. My work is characterised by dynamism, interaction and learning. In almost twenty years of international work, finding common ground, and generating commitment and ownership among stakeholders have become key aspects of my approach. I enjoy facilitating complex multi-stakeholder processes and have worked with very diverse and polarised groups and institutions. I use large group methods such as future search, open space technology, world cafe and appreciative inquiry and have worked with the founding fathers and mothers of these methods.

I am married to Lisette, who is also a partner in Perspectivity, have 2 daughters – both born on the 13th (just like me, my father and grandfather). I am a lover of water (swimming, diving…), and I play piano and didgeridoo. I also find it hard to choose between living in the city and living in the countryside.

What others say about Han:

As a biochemical engineer, Han is fascinated by complexity, combining and extracting each and every element to create something fundamentally new. His desire to make this world a little more loving has led him to shift his focus from physical to human matters and he is continuously engaged in studying the complexity of human systems.

With his sharp and open mind, he invites you to look beyond the commonplace and to take risks. Han uses inspiring processes to enable individuals to commit to their chosen target and be open to surprises. Han contributes passion, attention to detail and surprises.

Han Verhoeven

Questioning and listening with open mind and heart is key in my style of working. Combined with structured analysis and creativity, the workshops and training courses I design and facilitate are usually practical, full of insights and a pleasure to experience.

My passion is to assist individuals, teams and organisations in expressing their dreams, interests and values while listening to others. Searching and creating common ground leads to willingness to act.   ‘Be a contribution’ is my motto. I use strength based approaches like Appreciative Inquiry and Future Search. Enable appreciative understanding and self expression in situations of conflict has my particular interest.

I have twenty years of experience in organisational development and network building. I trained hundreds of professionals in the field of facilitation, learning and session design. I am a specialist in gender and security. I often work in intercultural settings and overseas.

I am an IAF certified Professional® Facilitator, Brain Central Learning professional and accredited Insights Discovery Practitioner. In 2012 I co-founded Perspectivity Enterprise.

What other people say about Han:

Han has elevated “don’t just do something, stand there” to an art when facilitating her sessions. It is no surprise that she is qualified to accredit facilitators for IAF. Her deep compassion for women and their roles and rights in society is truly heartfelt, and finds its expression in her training. Down-to-earth and practical, rooted in reality and inspired, is she always open to searching to find where the solution lies.

Jelle Troelstra

Since 1990 I have been working as consultant in the field of public management and policymaking. I support public authorities in policy development projects on spatial planning, environment, transport, water, nature, among other domains. I cover the complete range from visioning, formulating and decision making to implementation, with a focus on effectiveness of policymaking, and team and organizational performance.

My approach lies in integrating diverse interests of multiple stakeholders involved in public management for sustainable results for all parties: ministries, local governments, interest groups, corporations. I help clients formulate executable policies and legislation, by making them coherent and clear through a creative writing and communication process. In other occasions I support teams and individuals to meet their organizational and personal development needs.

My drive is to facilitate the exploration of new pathways to enable organisations to excel and grow to reach their goals. I help them to clarify their ambitions in development plans. As a nature lover, my drive is to look for sustainable solutions for the environment small and big. I am goal and results oriented, with an open eye for people and organization’s developmental needs.

I am educated in environmental sciences and have been trained in various approaches for organizational development and coaching.


Lara Minnaard

In the past years I have learned that there is an incredible amount of people with innovative ideas who truly make the world a little bit better. Whether those are scientists who do research that is socially relevant, or start-ups who bring innovations to the world or a local initiative in a neighbourhood. All of those ideas become relevant and start to come alive as soon as they are shared. Because of my background in and love for (competitive) debating, I soon realised that many of the techniques you train when debating are useful for a variety of other aspects of life as well. Whether this is about listening attentively, posing critical questions or formulating clear statements – to name a few. I am convinced that these skills are crucial for everybody, especially for the people who want to make a difference. Through debate I help people improve their listening, speaking and formulating (quickly and consistently) skills.

During my studies in Communication in Agricultural Development and later during my work at the University, I came into contact with dialogue, or, to put it more broadly, interactive processes and the facilitation of them. Processes where many of the techniques that I had gotten to know in the past years came together with attention for the content. After finishing my thesis around the influence of informal networks on the success of agricultural innovations at the Centre for Development and Innovation, I was still curious about the way in which these interactive processes worked. Now I am building on my current expertise about argumentation, presentation and listening techniques by becoming a Young Talent at Perspectivity. And hopefully, I can then say that I have helped to make the world a little bit better than it is now.

Lisette Gast

I have over fifteen years of work experience in fostering learning organisations and development cooperation.  With an academic background in communications, I gained experience with many facets of international cooperation in several countries, including Ecuador, Colombia, Bolivia, Tanzania, Ghana and Jordan. During my career I developed a passion for connecting the individual to the organisation through the use of meaningful participation and reflection.

I strongly support innovative learning and have designed and facilitated a range of processes, which include setting up evaluations systems, coaching, trainings, external evaluations and working with large data-sets.

I dare to say about myself that I’m creative and flexible in the application of creative participatory methods and tools.  I possess strong analytical skills and have an open and energetic personality.

What other people say about Lisette:

Lisette contributes a feminine perspective with flair. She is both surprisingly friendly and sharp as a needle. Very alert when it comes to mutual frictions, she likes to hold up a mirror to people, but is also willing to look in the mirror with you if she is part of the situation. Lisette specialises in reflection. No one is able to set up systems that make implicit situations explicit in quite the way that Lisette can. From this perspective, she works with organisations and people, helping them to develop further.

During my career, as an international development cooperation and social justice expert, change processes have always fascinated me. Over the years, I have worked in the Netherlands and internationally, including in Mexico, the United Kingdom, Ethiopia, Egypt, Israel and Palestine. I sometimes worked in fragile areas or with partners operating in conflict sensitive environments on issues related to human rights, corporate accountability, community resilience and natural resource management. In these complex settings I have witnessed the power of dialogue and bottom-up approaches, the urgency for systemic thinking, and the necessity for fair engagement, inclusion and the participation of vulnerable groups.

I strongly believe in the strength of diversity and something that drives me is bringing people together to cross-fertilize, to create a space for dialogue. Connecting people and nature is also one of my passions. I would say my approach is focused on appreciation and participation, and working towards common ownership. There are several methods that have inspired me along the way, amongst others the Work that ReconnectsDeep Democracy and systemic thinking. I also enjoy the process of analyzing and designing, to think in concrete steps without losing sight of the bigger picture. Perhaps that is why I like to work with the Sprockler methodology and tool: designing and conducting participatory narrative inquiries and evaluations.

I obtained a master degree in international development planning at University College London (UCL) and a bachelor degree in Public Policy, focusing on rights-based and participatory approaches, land custodianship and sustainable food systems.

In my free time, I am a business and human rights working group member at a Dutch Commission on Human Rights and a member of the United Nations Harmony with Nature knowledge platform. I also sing, dance and travel whenever I can.
