Siv Jøssang Shields has been a practising chiropractor since 1996, working with thousands of patients across more than 30 years of clinical practice. Her Master of Science in Physiology included participation in cancer research, and her work has always been grounded in a deep curiosity about the mind-body connection and the science of human healing.
She has been teaching Neurogenic Tremoring (TRE) since 2010, training directly under Dr. David Berceli — the physiotherapist and trauma expert who developed TRE. Together with Dr. Berceli and Alex Greene, Siv co-created Neurogenic Integration — the world’s first fully online, self-paced TRE provider certification programme. She has taught internationally in Germany, Estonia, Sweden, Hungary, Norway, and online globally.
Siv combines TRE, breathwork, HeartMath, and brainwave entrainment — bringing together clinical science and transformational practice to support nervous system health, emotional regulation, and lasting inner change. Her hypnotherapy training informs the guided meditations she creates — giving them a depth and precision in speaking to the subconscious mind.
She is an international speaker, co-founder of The Integrated Human and Neurogenic Integration, and co-owner of Voss Kiropraktorkontor in Voss, Norway, which she runs together with her husband Jason Shields.
Outside the clinic and training room, Siv is a beekeeper, dog trainer, gardener, and committed hiker.
