Oliver is the founder of the London Clinic of Nutrition, and a trailblazer in the UK’s integrative medicine industry for nearly two decades. He has helped over 25,000 people – in the UK and abroad – improve their health, with an eclectic and multidisciplinary approach spanning Nutrition, Naturopathy, Herbal Medicine, Functional Medicine, and Mind-Body medicine, and encompassing the lessons from thousands of hours of patient interactions.

His approach has evolved over the years and is unique in this field. After a profound spiritual awakening, he incorporated elements of spiritual, soul work, and energetic medicine to bring healing to mind, body, and spirit. For those struggling with complex illness, such as Chronic Fatigue or Lyme Disease, this has reaped astounding results. Each interaction with a patient is a partnership where he supports them to discover their purpose and reclaim their connection to their Self, which awakens their innate healing mechanisms. This process includes working with patients on inherited and developmental trauma.

He is currently working towards a qualification in Internal Family Systems (IFS), after attending workshops with Gabor Mate, Bessel Van de Kolk and Dr. Richard Schwartz.
