Lesley Quilty

Lesley has four decades of experience as a group facilitator and coach, and in working with altered states as a vehicle for transforming consciousness. She aspires to bring authenticity, courage, tenderness, and joy to all she does.

Lesley embodies a long-term immersion in a number of intersecting healing modalities. Respectful use of psychedelics and plant medicines in ceremonial settings, Buddhist Insight meditation, the Indigenous Red Road practices of Sundance and Sweatlodge, Conscious Connected Breathwork, Family and Organisational Constellations, Archetypal Psychology, 20 years as a leadership consultant and trainer, and 40 years living in an international intentional community have all been part of her path. She is also a professional red-nose clown and clown-doctor.

Her work with Synthesis began in 2021, as a Learning Facilitator and Guest Faculty on the Professional Psychedelic Facilitator training, and ultimately as a Lead Facilitator on the retreat team.

Everything she shares as a facilitator is rooted in her own committed personal practice and ongoing study.
