Dr. Liz
Liz is a psychedelic guide and integration specialist.
She brings deep compassion and lived experience to her work with individuals navigating chronic illness, fatigue, and emotional overwhelm. Her journey through chronic symptoms led her to discover the healing power of psychedelics, yoga, and holistic practices — tools she now shares with others seeking relief, vitality, and reconnection.
Grounded in the belief that we are not broken but already whole, Liz helps retreat participants integrate their experiences and reconnect with their inner strength. Whether working somatically, through breath, or with integration coaching, she creates a safe and affirming space for deep healing to unfold — body, mind, and spirit.

Karen Borremans (psychedelic integration support)

She is currently training to be a psychedelic-assisted therapist at MIND Foundation and already supports people in integrating their psychedelic experiences in their day-to-day lives. She guides people in therapy to ‘make meaning’ of the feelings, sensations and ideas experienced in an altered state of consciousness and therefore helps to increase the potential for personal transformation that psychedelics can offer.
