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.


Anna Kogut

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).

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

I am one of Perspectivity’s new junior partners of the Enterprise’s Young Perspectivity Pool. I have a background in Anthropology and Development Studies. I have lived in countries such as Mexico, the United Kingdom, Tanzania and am currently based in Amsterdam.

From my background in anthropology and huge fascination with languages, I am especially interested in creating understanding between people. Through words in the sense of writing, reporting, editing and translating but also in the sense of helping people understand each other to create a more inclusive and sustainable world.

I started at Perspectivity as an intern in October 2014. I greatly enjoyed my internship and I got to work on a lot of interesting projects with the fun other interns. For example, I co-developed SPROCKLER, an on- and offline storytelling tool that combines quantitative and qualitative data. Further developing and rolling out SPROCKLER is still a big part of the work I do. Next to that I work on a lot of different projects within Perspectivity.



Maurice van Hoek

I am Maurice. My professional drive is to achieve tangible results with a group of people. I sincerely believe that people are happier in their work when the actually achieve those tangible results. The context I work in is mostly government oriented or non profit. Currently I am active as a project manager in de Nijmegen Region, as a trainer for trainees and as a facilitator.

In the Nijmegen Region it is my job to achieve the financial collaboration between the healthcare companies (primarily 18 and 150 overall) and the municipalities (7). The trainees are trained in project management, advisory and communication skills.

I like to learn new things, meet new people, gain knowledge and achieve new insights. That is why I joined Perspectivity.

I like good food, nice music and an outspoken beer (wine is fine too). I have got three kids in the age of 11 (girl),12 (boy) and 14 (girl), a cat (girl) and a very nice friend (girl – who is the mother of my children).

About the picture: I am the guy on the right.

Michael Donnelly

I am a trainer, facilitator, process designer, presenter and organiser of study tours and events.

After running a Belfast based non-profit for some years, I founded Second Nature in 2005. Together with associates I designed and delivered innovative approaches to running stakeholder engagement processes and strategies for sustainability. In 2012 I decided to join the Perspectivity Enterprise.

My specialisation is Large Group Interventions, using techniques such as Future Search, Open Space, World Café, Appreciative Inquiry and ICA’s Technology of Participation to maximise the effective participation of all those who have an active role to play.  In 2012, for example, I used Future Search to work with communities in Darfur, Sudan to develop peace building strategies and to work on the issue of alcohol and drug misuse in Belfast.

I also work in the field of sustainability. I am especially focused on enhancing organisational capacity to get to grips with this complex issue and to introduce change processes to make sustainability a successful business strategy. In 2008 I introduced a global framework for sustainability to Ireland, called The Natural Step and use this regularly in my work.

I am based in Northern Ireland where I live with my wife Tara and four children.

What other people say about Michael:

Michael is an optimist. He holds the gift to analyse and find the right words to describe each situation.

Monique Janmaat

Ever since I can remember I have been fascinated by how people interact and work together.  That is why I graduated in organisational psychology.  And that is also why I do what I do: I facilitate collaboration and learning for individuals, teams, organisations and systems to help them improve performance and accomplish their goals.  My training and facilitation assignments are related to strategic planning, leadership, performance management, organisational change, training and facilitation, all aimed at developing people, organisations and the wider environment.  I have been based in Tanzania since 1999, and I work in many different countries across a diversity of cultures and interests.

My approach is innovative and very participatory, and aims at increasing self-management, not only during my interventions, but also afterwards. Although differences exist, I try to help people discover common ground.  Raising awareness and making use of what is already present, successful and effective provides a solid foundation for improvement and change.

No matter how challenging the issue, participants always have something in common. When dealing with issues and multiple interests, I use large-scale interventions such as open space, world café, future search and appreciative inquiry. And most important of all: I love what I do.

What other people say about Monique:

Monique sparkles. Her untameable energy, coupled with boldness, always produces surprising contributions. Her original views are contagious; she is always looking for new opportunities and carries people along, in search of a “better world”.  Monique is always looking for depth, unafraid of what she might encounter. Her thirst for professional growth is virtually unstoppable and she is always willing to share her expertise. This is because she really cares!

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.
