Celina De Leon M.Div, has 20 years of experience in the field of psychedelics with particular experience working with various indigenous and spiritual lineages. Her long-standing relationship with the Kamentsa indigenous community of the upper Putumayo of Colombia informs her perspective on valuing how indigenous knowledge contributes to our understanding around the spiritual and therapeutic uses of psychedelic substances. She is also a Fulbright Scholar and underwent partial chaplaincy training at UCSF through the clinical pastoral education program. Celina will be a senior guide for the experimental sessions and will create a longitudinal contemplative learning program to support participants throughout their involvement in the research studies. She is excited to create this program within a spiritual care framework while celebrating the intersection of science and spirituality and the importance of diversity and inclusion.
