David McNamara

David comes from the humanitarian sector, providing technical services for non-profit crisis-response agencies in the developing world. He has completed his master’s degree in Geographic Information Systems and has been working for an international NGO.

David is pivoting to offer his operations and engineering skillset to the facilitation of healing retreats to those who may benefit. A decision from the heart!


15 years ago, David suffered a major life-crisis. Psilocybin mushrooms (then legal in Ireland!) played a huge part in his recovery and allowed him to move past old destructive patterns of thinking and experience divine connection to nature.

David has since been exploring the remarkable healing potential of these organisms and has gained the experience to facilitate other’s access to this natural medicine.

The Wounded Healer

He is currently in his 3rd year of training as a Transpersonal Therapist at ICSS Dunderry Park. David has counselled many people using these effective techniques and has facilitated group journeys.

David is a passionate advocate of psilocybin mushrooms as master healers. He runs the community website Shrooms.ie  to organise events and campaign for an end to psilocybin prohibition in Ireland.
