Our team

Caroline Rennie | Switzerland

Caroline worked for decades using participatory practices to build community and collaboration in companies, supply chains, government, and communities of practice. My goal has been to help people improve their individual and collective situation, including the environment, society and non-human beings. I do this by working with groups to speak with intention, listen with attention, and reflect together on what they have heard. In this way changes, both subtle and obvious, manifest for the group as a whole. This often leads to change without pain: change for the better that is seldom noticed until attention is brought to it.

I am joining the team in Karlskrona this year because it combines the sustainability and participatory practices threads that carry through my life. I can’t wait to be together in learning and exploration again! @rennierenewed

Iker | Spain

I’m originally from the Basque Country in northern Spain, but I now live in Karlskrona, where I’m exploring systemic perspectives and leadership for change. With my background in engineering, I enjoy working on product design as an agent of change, and I am trying to find ways to create a more multidisciplinary and broader engineering perspective. Being part of AoH is one of the ways in which I am doing this.

Alekos 

Hi, my Name is Alekos and I‘m currently studying the masters programme in Strategic Leadership towards Sustainability at BTH. I am here because I want to learn and grow in facilitation, self-hosting, strategic planing and teamwork.

My passions span from creating new initiatives, inviting people, holding space and processes, to cooking and music. In my experience, the change that is needed happens when we are hosting it, together. This translates into my engagement in Commoning networks and practices – stories of collaboration and self-organising that I want to bring to the world.

I studied Philosophy and Arts, usually ask deep questions and love to co-create. In co-organising this training, my intention is to become part of the Art of Hosting-community and practice my project-management-skills.
