“There is no coming to consciousness without pain. People will do anything, no matter how absurd, in order to avoid facing their own Soul. One does not become enlightened by imagining figures of light, but by making the darkness conscious.”   –  Carl Gustav Jung

The Breathwork Group Series is:

The Breathwork Group Series a unique five-week, fully supported transformational process, designed to open to life at the core level, and start living it fully. It offers the groundwork for true inner change. The Series requires attendance at all five sessions, missing out on maximum 1 session.


The process deeply activates the connection with yourself and others, and includes full Breathwork sessions (inspired on Holotropic Breathwork) and a powerful mix of deep psychological and embodied practices that elicits flow states. Through the experience of this incredibly opening work – you will receive a deeper understanding of your energy and its drives, blocks, motivations, longing, and love.

Each week, for five weeks we will come together to breathe and feel, to release and heal parts of ourselves and integrate the learnings. We will inquire and open our curiosity to the unknown, meeting our layers of protection and parts of ourselves that we supress, deny or reject. You will receive a direct experience of integrating what Carl Jung called the "Shadow". In search for wholeness we will enjoy each other's support and inspiration, being with the same focus, in service of love and truth.

Our mission is to help inspire, catalyse and support grounded personal transformation, through embodied practices. We put strong emphasis on integrating your experience and apply these new skills and ways of being, immediately. You will receive many cutting–edge tools in the personal development space, and supportive assignments to integrate and further explore your experience and improve key psychological traits like presence, openness to experience, resilience intuition and self-reflection.

The series is led by Katrien Franken, together with the Open Up team. What excites her in creating the Series, is to see the possibility for true change. To offer the space for embodied work, physical experiences and meaningful relating with a purpose to bring about a more awakened, enlivened, conscious world. "It is a profound honour to facilitate breathwork, holding the space and supporting those undertaking deep transformational journeys."


"After attending the DO lectures in Wales, I decided to find a place in NL to do a breathwork course. I came across The Series of Katrien and it appealed right away. The themes, the length of the course, working in a group and yes, there was a last minute spot available. I had to go! Katrien offers a course that is much more than just breathwork - she shares in-depth content in a nice flow of exercises that challenges on many levels with a great balance between individual experience and group dynamics. I loved the support she and her team offe-red during the program. With even greater curiosity looking forward to the second edition."


Nienke Dijkstra – Speakers Coach at TEDxHaarlem – April 2019



"Katrien is an incredible, intuitive teacher, and I feel very fortunate that I’ve had the opportunity to take part in the first Breathwork Series with her. The Breathwork Series was truly transformational. The strides I made in my personal and spiritual development in that short time as a result of Katrien’s guidance, the breathwork, and the sharing we did in groups was remarkable and powerful, and no other practice has had such a profound impact on me, both physically and emotionally. In all of the sessions, Katrien creates a trusting, safe space for her students to open up, get vulnerable, explore the stories they tell themselves, and dive deep into their inner worlds. Under Katrien’s gentle guidance, I felt completely safe to let go and explore my truths. As a result of the Breathwork Series, I feel that I know myself better, I trust myself more, and I’ve made some positive changes in my life that needed to be addressed long ago."

Breathe, Open, Flow!

As human beings we have something in common; we breathe. But most of us don't use the full lung capacity due to stress or fear, anxiety, trauma.. This disrupts our flow in life and makes us feel disconnected from our body and authentic essence. We numb our pain and shut down our expression of truth and aliveness. We block ourselves from receiving love and abundance from others and the world around us, with consequences such as depression, addiction, hyper-independence, burnout and relationship dysfunction (to name a few). This Series is carefully designed to consciously charge your body with oxygen (energy) that releases the tension from the muscles where energy can start to flow again. As we'll dive deeper into our breathing, we will meet the pleasure of nourishing and restoring our body, of digesting and releasing our emotions, creating a possibility for growth and change. 

Conscious group work

A small group can have a huge impact on the world. Be one of them! In this conscious group work we are the mirror for each other, reflecting back who we are. In this intimate exchange we find our way into truth and authenticity. We'll meet the pleasure of nourishing and restoring our energy, and of grounding ourselves in becoming more resilient, present and powerful in the world. We offer each other authentic relationship and are changed because of it. One step at a time - one breath at a time we can start sharing a vision to catalyse a genuine change in consciousness, together. ​​
