Susannah Britnell

Susannah Britnell

Susannah has a BSc Honours Degree in Physiotherapy from Manchester University, England, and a Diploma in Manual and Manipulative Therapy. She has integrated pelvic floor physiotherapy and pain science (biopsychosocial approach) into her practice. Susannah works in Vancouver, BC, Canada at the Centre for Pelvic Pain & Endometriosis, an interdisciplinary program for persistent pelvic pain at the BC Women’s Hospital and Health Centre and in private practice. Susannah’s passion is to help women overcome years of pain and disability. A majority of her patients have had Pelvic Girdle Pain (PGP) for many years, if not decades. By teaching other therapists the Rost Therapy method, Susannah hopes to break the cycle of chronicity, by ensuring more and more women have their PGP managed well in pregnancy and postpartum.

Rost Therapy – Pelvic Girdle Institute would not be possible without the continuous support and hard work of our team of teachers (in the Netherlands and abroad) and staff.
