Training & qualifications

Working with care begins with
continuing to learn.

Mariëlle combines her training in NEI and Reiki with further learning about trauma, resilience, self-regulation and psychosocial themes. This allows her to look beyond a particular approach and give thoughtful attention to the whole person.

The foundation of Praktijk IK

NEI and Reiki
come first.

Praktijk IK focuses on NEI and Reiki sessions, which is why these qualifications are presented first. The other certificates provide valuable additional depth: they show that Mariëlle has broadened her knowledge in areas related to emotions, stress, loss, resilience and safety.

A certificate cannot tell you everything about a practitioner. It does, however, show that knowledge has been developed deliberately and that Mariëlle continues to invest in careful, person-centred practice.
