Our Team
Luea Ritter
Co-founder and Creative Steward
I thrive within ambiguity and complexity and gravitate towards integral, participatory, and embodied practices.
Luea Ritter is a transformative process steward, systemic coach and action researcher whose work weaves together innovation, leadership processes, transformative change and healing to support collective transformation. She brings over two decades of international and cross-cultural experience in personal, organisational, and cultural development, working across multiple sectors and scales to help groups and organisations co-create the conditions for resilient and regenerative approaches.
As co-founder and steward of Collective Tranistions, Luea cultivates spaces for systemic awareness and collective capacity building, fostering conditions to help groups navigate complexity and maintain transformational shifts. She is also a vital driver of the World Ethic Forum where she stewards the Firekeeper Circle process, and the participatory action research, as well as the Youth Negotiator Academy where she supports Youth Negotiators with systems-awareness, mental health and community building for the three UN Rio Conventions and their respective negotiations processes. As a co-founder and chair of Nile Journeys she helps bridge transboundary dialogue and regenerative collaboration in the Nile Basin.
Across all her work, including PhD research and clients such as the World Future Council and the Global Ecovillage Network , Luea’s inquiry centres on fostering coherence in social fields - enabling individuals, organisations and ecosystems to navigate the complex challenges of our times.
Natalie von Tscharner
Project Manager
I believe that a deeper self-awareness leads to more genuine and effective connections, forming the foundation for sustainable, collective change.
I was excited to join Collective Transitions as Project Manager in January 2025. Since 2013, I have worked in participatory processes, project management, and group facilitation, always aiming to create spaces where people can connect meaningfully and feel secure.
My background in sociocultural animation, mediation, and coaching, along with recent training in trauma-informed practices, helps me ensure that every process respects and works with each individual’s capacity and resilience.

Kate Lewin
Communications Lead
Joining Collective Transitions means I can engage in a continuous exploration of practices and values that are very important to me.
I’ve worked for over a decade as a senior communications lead and campaigner for sustainability platforms, charities and human rights causes.
Alongside this, I am slowly training for a MSc in Integrative Psychotherapy where I’m developing a relational, developmental and anti-oppressive practice which honours our full intrapsychic and interpersonal understandings and relationships with people, our environments, and with systems.
Being part of Collective Transitions is joy therefore, as it sits at the intersections of my two passions meaning I’m able to get nerdy about websites, designs and newsletters, whilst also nurturing my personal interest in our capacity and potential as individuals and collectives.
Mira Majewski
Coordinator of In-Person Programs
I’m grateful to be part of Collective Transitions as a facilitator and organizer of in-person training in Switzerland, after completing both the intro-training and the facilitator training at Collective Transitions.
Alongside this, I work in my own practice as a Somatic Experiencing® practitioner, supporting individuals as a somatic coach and trauma therapist. I also co-founded Waldhaus — a community and seminar house in Switzerland— where I host events, organize gatherings, and help create a vibrant learning space for inner and collective transformation.
I’m deeply inspired by practices that expand our capacity to sense, stay present, and engage with complexity. This work is part of a larger calling for me: building bridges between embodied inner work and systemic change, and contributing to a regenerative culture.

Ursina von Albertini
Board Member and Sounding Board
Questions of human transformation and development—both personal and societal—have always been at the center of my interest. That’s why, as an aspiring therapist, I chose the path of Gestalt therapy.
Creative and experimental approaches within the therapeutic process resonated with me. Back then (1970), our non-dogmatic way of working was considered avant-garde. Later, I expanded my field of work to include organizational development.
I am deeply inspired and joyful about my more than 25 years of involvement with a small school in Senegal, West Africa. In 2001, I traveled to Senegal to dance. What emerged was a vibrant and powerful dance between our African partners at the school and friends in Basel.
Our guiding stars? How do we meet each other at eye level, given our vast differences in education and culture and the deeply ingrained legacy of colonial history? How do we cultivate a foundation for respectful and appreciative encounters? How do we build bridges and find new paths when strangeness and misunderstanding threaten to dominate? And to stay with the image: how do we keep rediscovering a lively, shared dance and celebrate together? Our collaboration has flourished for over 25 years. I see the richness of these experiences as fertile ground for the many challenges that lie ahead.
In the meantime, I have become part of the grandmother generation and am delighted to support younger, creative, and courageous individuals in the upcoming transformations through Collective Transitions.
Andrea Klepsch
Board Member and Sounding Board
Collective Transitions is a being which I love to nourish as a member of the Board of Directors. To gift it with the knowledge and wisdom which flows through my body, enriched with my experience and my capacity to search for and explore new paths.
I sense the importance to open ourselves – individually and collectively – to the beauty as well as to the pain of transition. And here is where I sense our common vision and the opportunity to follow the great calling.
Cultivating deep, in the web of lived, rooted humanity, has been my journey for 35 years. I am guided by the insight and experience that life is a dance of relations - relating with ourselves, with others, with communities (be it families, villages, NGOs, companies), relating with all living beings and relating with the not knowing. My north star is to co-create peaceful, just and sustainable organisations and societies. I do this in a lot of voluntary as well as a business coach. From 1993 – 2023 I was founding CEO of an agency focused on sustainability consulting and communication.
about Andrea Since November 2024 I am certified IDG Ambassador – Kilimanjaro cohort. As a firekeeper (since 2023) of the World Ethic Forum I am co-creating and researching a culture of caring based on radically shared aliveness. The movement “Homes for Humanity” I support as an Earth Ambassador since June 2024. I belong to a little valley south of Munich, Germany, where social and organic farming is deeply rooted in the hearts of the farmers.
Felix Oesch
Board Member and Sounding Board
I am an organizational development practitioner who began my work in the late 1970s—among the very first to take the initial steps toward organizational development in Switzerland—and today I am retired.
Yet when Natalie and Luea called upon me under the banner of organizational development, I was glad to respond: we need young, passionate, and dedicated people to embrace this field and tackle its many developmental challenges. I firmly believe that Collective Transitions is not just valuable but essential.
As a former Head of Human Resources and, more recently, as an independent organizational development and management consultant, I have much to contribute in terms of insights and thoughtful reflection.
Thanks too, to our wonderful, independent collaborators: Julien Leyre and Alexa Lux.
Our History
Collective Transitions began with a question
After an intense phase of inner and outer transformation, our co-founder Luea Ritter asked:
“How would we do this collectively? How can we transition together — to truly address the intertwined challenges of our time?”
Luea’s inquiry was rooted in experience. She had witnessed that even profound individual transformation did not always translate into cohesive, resilient teams. Groups working for social or systemic change often met edges and tensions in relationships and collaboration that could endanger their most important work.
This question has guided Luea ever since. It evolved into a deep exploration of what is required for collective transition - how groups, organisations, and societies can move through complexity with awareness, coherence, and care.
Her work increasingly focused on supporting cross-sector and cross-cultural initiatives, and those navigating the intertwined crises, or polycrisis, of our time.
Collective Transitions was born
In 2018, Luea met Nancy Zamierowski through a mutual friend. Their first conversations quickly revealed a shared depth of vision and a mutual recognition of purpose. Together, they began shaping what would become Collective Transitions, envisioned as an Action Research Hub exploring systemic change through practice, inquiry, and community.
Over the next six years, the collaboration flourished:
Publications included a co-authored book, papers, and chapters by Luea, Nancy, and contributors, as well as a range of articles and reflections were published.
A full curriculum for Systemic Constellations for Societal Change and Systems Sensing was developed.
Numerous courses and trainings, both online and in person, were held, led primarily by Luea with Nancy’s support.
Community gatherings such as The Twelve Nights, Seismograph Calls (during COVID), and ongoing practice spaces cultivated a vibrant, international learning community.
Collective Transitions also contributed to long-term collaborations with respected partners including the Youth Negotiator Academy, the Global Ecovillage Network, and the World Ethic Forum.
A wide circle of partners, contributors, and practitioners joined along the way, bringing gifts in branding, editing, facilitation, sensemaking, and communication.
The first six years were marked by deep learning, experimentation, and a continuous refining of practice and purpose.
A Conscious Transition
At the end of 2024, the co-leadership of Luea and Nancy came to a conscious and graceful close as Nancy felt called to new directions. After a period of reflection and discernment, Luea recognised that her journey with Collective Transitions was far from complete, in fact, it was entering a new phase and calling her forwards. This moment marked the beginning of a renewal cycle:
A Swiss-based association was created to anchor the organisation’s next phase.
A new team and faculty are being cultivated to deepen and expand the work.
The evolution of Collective Transitions continues with clarity, integrity, and a vision for long-term stewardship.
To accompany this transition and strengthen the foundation of this new phase, Natalie von Tscharner joined Luea as Project Manager in 2025. Natalie first encountered Collective Transitions in 2024 through one of Luea’s constellation courses and was deeply moved by the work’s depth, coherence, and integrity.
Together, Luea and Natalie carry forward the unfolding of Collective Transitions, grounded in a shared vision, complementary strengths, and a commitment to cultivating collective intelligence and transformation.
Now, Collective Transitions continues to grow alongside the question:
“How can we, together, embody the transitions our world is calling for — with coherence, courage, and care?”
