Marieke de Leeuw

Overview

Marieke de Leeuw is the founder of Het Stille Midden and a former general practitioner based in the Netherlands. After experiencing burnout in medical practice, she shifted her focus toward inner work, personal development and consciousness-based guidance. Her work now centres on supporting adults who feel stuck in chronic stress, emotional pain or disconnection, helping them return to a grounded sense of self and inner clarity.

Through Het Stille Midden, Marieke facilitates guided psilocybin truffle ceremonies, microdosing programmes and integrative coaching. She approaches this work as a path of self-inquiry and healing rather than treatment, combining her medical background with experiential and reflective practices. Her style is calm, direct and responsibility-focused, with strong attention to safety, preparation and integration.

Best for

Marieke’s work is suited to adults seeking personal growth, emotional healing or spiritual development. It may be especially relevant for people experiencing burnout, anxiety, depressive feelings, trauma-related patterns or addictive behaviours, as well as those curious about psychedelics in a structured and well-held setting.

• Adults dealing with burnout, stress or emotional overwhelm
• People seeking insight into trauma, habits or life direction
• Individuals interested in guided psilocybin or microdosing trajectories
• Clients open to combining coaching with inner and spiritual work

Approach

Marieke works integratively, combining coaching, body-oriented practices and psychedelic-assisted processes. Her methods include parts work inspired by Internal Family Systems, focusing, trauma collapse techniques, breathwork and embodied awareness. She emphasises listening to the body and inner signals as gateways to transformation.

Psilocybin truffle ceremonies are embedded in a clear process: intake and screening, preparation, the guided ceremony itself and structured integration afterwards. The ceremonies are held in a calm, supportive environment with music and minimal external stimulation. Integration sessions focus on making sense of insights and translating them into everyday choices and behaviour. Microdosing is offered as a gentler, longer-term trajectory combining guidance, structure and reflection over six weeks.

Support

Marieke offers individual and group truffle ceremonies, microdosing programmes and coaching or integration sessions. She provides clear screening and outlines contraindications, including certain physical conditions, psychiatric diagnoses, medication use, pregnancy and active addiction. She is transparent that her work is not a replacement for medical or psychological treatment.

She is a member of The Guild of Guides and works within their ethical framework, including supervision and ongoing training. Clients are supported before and after ceremonies, with an emphasis on responsibility, confidentiality and long-term integration rather than peak experiences alone.
