Pilvi Ahtinen
Craft teacher and TWB volunteer, MA

My name is Pilvi Ahtinen and I have a master’s degree in education at the University of Helsinki, majoring in technology education. I have also studied industrial design (B.A) and now I am expanding my knowledge by studying for a master's degree in service design.

With eight years of professional teaching experience in the field, I have gained experience in design thinking, technology education and STEAM teaching. Currently, I work as a design and craft teacher at the comprehensive school. In addition to my teaching role, I train craft and design teachers and mentor teacher students.

I have previously worked and studied abroad. The latest experience I have gained in Uganda (2023) where I worked as an education advisor through teachers without borders network. In Uganda, I trained teachers at the refugee settlement while building teachers’ capacity in a functional, play-based learning approach.

I love to be near nature. I often find myself walking or skiing through the forest. I also like to relax while cycling and kayaking. Nature has a calming effect which I truly appreciate.

Mia Halme
Documentary filmmaker and yoga instructor, MA

I have graduated with a Master of Arts degree in film from the University of Arts and Design Helsinki and have been a documentary filmmaker for over 20 years. I have also worked as a lecturer and professor of documentary filmmaking at the same university. As a teacher, I found mentoring and creativity exercises essential, as I believe they are necessary for everyone. With the film students we completed exercises in the forest, and used, for example, dreams as part of the film development process.

As a director, I combine the knowledge provided by research with artistic expression. My films are characterized by acceptance and appreciation, whether it concerns humans or other creatures of nature. The subjects of my films have ranged from children in foster care to Sanna Marin's government, but the approach has been unified by a respectful perspective. My latest film ‘Fabulous Cow Ladies’, completed in 2024, is a half-hour forest bath that tells the story of three cows living in a forest pasture.

I am also a trained yoga instructor and passionate about practicing modern dance. I try to include bodily knowledge into my work as a film director. My favorite is teaching a yoga class in the forest!

Heli-Maija Heikkinen
History and social studies teacher, writer, and TWB volunteer, MA

I am a history and social studies teacher and a writer living in Loppi, Finland.

I have a Master of Arts degree and my major at university of Oulu was Finnish and Scandinavian history. I have also studied creative writing and drama education as well as sustainable development.

I have worked as a teacher for over 20 years. I have published three novels: Viestikyyhkyupseeri (Minerva 2014), Asema (Warelia 2022) and Grilli (Warelia 2025). I have co-written the student union leader's guide (Opinkirjo 2018) and the Peace Education course together with Riikka Pöyhönen (Teachers Without Borders Network 2025).

Since 2022, I have been an active member in the Teachers Without Borders network and have worked as a volunteer in Uganda (2022) and as a distance educator in Cambodia (2023).

It is important for me to maintain faith in everyone's own possibilities for influence and in the preservation and development of democracy. I want to be involved in making the world a better place for all of us. I personally find rest and peace in nature and the company of close people and animals, as well as in creative work. As a teacher, I know that I wake up every morning to do meaningful work.

Anu Kosonen
Animal-assisted mind coach and nutritionist, MSc

In my training you will dive into a peaceful presence and you will feel connected with nature and animals. You will get tools for your personal stress management and well-being as well as our teaching in and out of the classroom. After my session you should be able to use nature- and animal assisted tools in your own work and you know where to find more tools to do so.

I am Nutritionist (MSc), Stress management coach, Forest mindⓇ coach, Animal assisted coach and Garden therapy coach. My session will be arranged at my home farm in Loppi. Our farm is mainly a forest environment with horses, sheep, chickens, dogs and bunnies. We have build and are still building the environment to support the well-being of humans, animals and nature equally. Responsibility and environmental issues are high on our priority list because I believe we are one with nature and that without nature we are lost.

Almost all my activities I do at work and free time involve forest, culture and animals. These things keep me grounded and healthy and my safe place is always with horses, especially with the herd. I welcome you to join us to explore your true nature and find new ways to bring nature into your teaching.


Tiina Seppälä profile image
Tiina Seppälä
PhD student and educator, MSc

I have Master’s degree in Animal Science and I’m currently a PhD-student in University of Helsinki and the Doc­toral Pro­gramme in Sus­tain­able Use of Re­new­able Nat­ural Re­sources. Horse nutrition is the main subject of my Thesis. Throughout my studies, I have been interested in the natural behaviour and welfare of domestic animals.

I work as a farmer in our family farm, Pelto-Seppälä, which is over 300 years old. Our farm is home to almost 100 mother cows and their calves, who live in the cowsheds, where the cows are kept in groups and unchained through the winter time, and on the pastures in the summer. All our cows are fed with products from our own fields. We try to provide our animals resources for natural behaviour the best way we can. Besides cows, we also have ten horses living in our place, mostly the national cold-blooded Finnhorses.

For me, animal welfare is not just the absence of negative aspects, but also the animals ability to have positive emotions. The most rewarding part of my job as a farmer is to see the cows and the horses able to live in herds. I’m grateful to learn to read their behaviour - as part of nature’s creatures. Animals are, like scientifical studies have shown, the best mirrors for our own mind and emotions. It is not just us and them. We have a connection- whether we see it or not.


Riikka Pöyhönen profile image
Riikka Pöyhönen
History and social studies teacher and TWB volunteer, MA

I have a master of arts degree from the University of Oulu. I studied at the history department and my major was general history. I have also studied drama education and psychology.

I have over twenty years of experience teaching history and social studies in a Finnish junior high school. Peace, democracy, youth participation, and tolerance have been the main focus of my teaching.

I have made peace education materials for teachers without borders and trained teachers and NGOs in Uganda and Cambodia (online). We have planned a Peace Education course for Finnish schools with Heli-Maija Heikkinen.

My favourite place is the forest: sleeping in a hammock and having a swim in one of the thousands of lakes first thing after waking up.

Pauliina Ruokokoski
Art teacher and artist, MA

I am an art teacher and artist living in Kirkkonummi, Finland.

I have a Master of Arts (Art Education) degree from Aalto University and several specialized studies in the therapeutic approach to art.

I have worked with people of various ages. In early years education I have developed children's art education using the Reggio Emilia approach. I have participated in two seminars in Reggio Emilia, Italy (in 2002 and 2009).

In art education with teenagers and adults, I often use the therapeutic Empowering Photography method as a tool for self-expression. Natural materials and recycling are essential elements of my art teaching.

My dog Laila (Border Collie), works with me in elementary school, where I implement dog-assisted teaching.

Alongside teaching, I create my own art. My works are primarily assemblage and mixed-media pieces, combining various materials and techniques. I display my art annually in several exhibitions across Finland.

I enjoy spending time outdoors in nature throughout the year. However, summer is my favorite season because I can sleep in a hammock and swim in the lake daily.

History and social studies teacher, vice principal.

I graduated from the University of Oulu in 1997 with a degree in history and has continued to broaden my qualifications, including studies in special education. For more than ten years I have also worked as a vice principal. I have worked most of my career as a teacher in lower secondary school, but I also have experience teaching in upper secondary school. Almost thirty years of work are already behind, so experience and vision can be found:)

Beyond the classroom, I have experience in football both as a player and coach, and I enjoy gardening, hiking, birdwatching, and friendly games of backgammon.
