Dr Oliver Bernath brings world-leading expertise in neurology and sleep medicine to Reborne Longevity, anchoring our belief that longevity begins with understanding the whole person.

He is Consultant Neurologist and Sleep Disorders Specialist at:

Guy’s and St Thomas’ Hospitals NHS Foundation Trust

Queen Victoria Hospital NHS Foundation Trust

Dr Bernath trained with pioneers in neurology and sleep medicine at the University of Chicago and the University of California San Francisco, completing fellowship training in sleep medicine at UCSF and Stanford. He later led the Northern California Sleep Disorders Centre at Kaiser Permanente before returning to the UK.

Sleep as the Window to Longevity
Sleep is not just rest. It is a neurological process that shapes cognition, metabolism, emotional resilience, cardiovascular health and long-term brain ageing.

Dr Bernath’s background in neurology, neurophysiology and sleep medicine allows him to see sleep as a diagnostic gateway. Insomnia, fragmented sleep or REM disturbance are often signals of deeper metabolic, psychological or neurological imbalance.

At Reborne, this aligns with our 360° philosophy. We assess brain, body, behaviour and environment together, not in isolation.

A 360° Approach to Human Health
Beyond clinical medicine, Dr Bernath has led healthcare strategy work at Strategy& and McKinsey & Company, designing integrated care systems and national health strategies. This systems-level thinking informs his clinical practice, connecting data, physiology and lifestyle into one coherent picture.

His approach is simple.
Optimise sleep. Understand the nervous system. Align the whole organism.
