Certified mindfulness trainer Jolien Posthumus pioneered mindfulness practice in the cultural sector in The Netherlands. Mindfulness Based Techniques, and scientific insights in the fields of psychology, education, neuroscience and polyvagal theory (trauma informed) among others are key to my professional practice.

With 18 years of health practice, working as a certified mindfulness trainer and working in in the cultural sector, I pioneered mindfulness practice in museums in the Netherlands. I developed bespoke mindfulness programs for for, among others, the Van Gogh Museum, the Museum of the Mind and several more.

I’m a registered (2015) highest degree mindfulness trainer and I continue to deepen my traineeship in all its diversity. In addition I am chair of the mindfulness association Taskforce Diversity and Inclusion to make mindfulness available for everybody who is interested in mindfulness. In 2018 I was part of organizing committee of the 3-day international mindfulness conference.

For cultural and healthcare institutions I develop Mindfulness Based Programs and I am available as (trauma informed) consultant for the development of Health & Wellbeing programs for museum visitors, young adults, adults and healthcare professionals.
