Franklyn Sills MA, RCST, UKCP


Franklyn has been a major influence in the worldwide development of a biodynamic approach to craniosacral therapy. He has been teaching in this field for over 30 years, and has influenced many current teachers and trainings throughout the world. He has presented at many Conferences over the last twenty years and his books, Foundations in Craniosacral Biodynamics Volumes 1 and 2, are seminal texts in the field.

Having originally studied medical sciences, Franklyn has a long history of study and clinical practice in psychotherapy as well as in craniosacral therapy. His original psychotherapeutic orientation was in humanistic psychology, working with neo-Reichian and pre-natal and birth psychotherapy. He has studied and collaborated with Dr. William Emerson, one of the prime developers of pre- and perinatal psychology. Franklyn also lectures in the Core Process Psychotherapy Training, a mindfulness-based psychotherapy program developed at the Karuna Institute, which he co-founded. He offers his expertise through presentations on Buddhist psychology, pre-natal and birth psychology, personality formation, mindfulness practice and trauma skills. He also teaches the neurobiology of mindfulness, stress and trauma, and he has brought this into the Institute’s Trainings. Franklyn has helped to develop the integrated paradigm of being and selfhood used in the Core Process training.

Franklyn was a Buddhist monk under the most venerable Taungpulu Kaba Aye Sayadaw of Northern Burma, and also studied in the Zen and Taoist traditions. His experience in the cranial field has convinced him that the body must be included in any form of therapy. His published books include The Polarity Process, Foundations in Craniosacral Biodynamics vol. one and two, and Being and Becoming, Psychodynamics, Buddhism and the Origins of Selfhood.
