SISU Mindfulness

About SISU

Get the most out of yourself with ‘stoic perseverance’

The word SISU is Finnish and quite untranslatable. The closest comes ‘stoic perseverance, which makes it possible to get the most out of yourself and realize the impossible’. SISU is about letting your actions do the talking.


SISU Mindfulness was founded by Jorien Weerdenburg. Her mission is to bring mindfulness out of the conceptual into everyday life and make it practical and accessible to everyone in the business community who want more balance and focus. She works as director of Organisational Transformation at IG&H and is a mindfulness and meditation teacher certified by Yoga Alliance International.


SISU is co-created by Nina Merrens. She is a leadership coach and team trainer since 1995, working both in the corporate sector and for the United Nations. She is a guest lecturer since 2001 at Passau University on intercultural awareness and a coach at the High performance leadership programme at IMD business school in Lausanne. She specializes in intercultural awareness and teambuilding, personal leadership development and the use of (metta) meditation.


Kirshna Raja is a certified yoga teacher and therapist, hailing from a family of traditional yoga practitioners in South India. After spending nearly 25 years as a marketing professional, he joined SVYASA Yoga University in Bangalore. He has been conducting stress management through yoga and meditation for IT companies in Bangalore, and is the founder of the Himalayan Yoga Retreat & International Yoga school in Cambodia.


They all have worked or still work in the business world and can therefore easily bridge the gap to the daily situations and challenges that the people in your organization encounter. What brings them together is their passion for making mindfulness and meditation accessible in everyday life.
