Tamara Slock

As a former nurse, Tamara realized that the compassion she had for her patients was a big part of the healing process. She started following the path of Yoga, became a breathworker, bodyworker and Reiki practitioner, exploring different pathways for holistic wellbeing. At Beckley Retreats, she uses music and various healing practices to help facilitate ceremonies. Tamara has studied plant medicine with a Mestizo Maestro and is currently studying under a Shipibo Maestro from Peru. She is the co-founder and manager of Mother’s House, where she supports research and conducts psychedelic ceremonies. She also works closely with ICEERS, organizing workshops on harm reduction and safety protocols for facilitators working with psychedelics.

Over the years,Tamara has witnessed many people heal their trauma with the help of psychedelics. She’s driven to enact a balance between therapeutic practices and indigenous shamanic teachings. For her, it’s not a job—it’s a calling and a way of life.“We can provide many tools, but in the end it is up to you. You are the medicine. A change in perspective is a change of life.”
