Dr Damien Downing:
He was born in St Ives, Cornwall, where for 100 years artists have gathered for the exceptional light.
Dr Downing's new book, Coherent Health – The Power of Light and Water, is out now, revealing the “magic” quantum interaction that enables life.
As well as the benefits of sunlight and photobiomodulation (PBM), he has interests in environmental pollution of both matter and energy – both addressed in his new book, along with circadian rhythm optimisation and a new understanding of melatonin.

Personal Assistant
"Ula Lipińska is Dr Damien Downing's personal assistant on Mondays and Tuesdays. If you call the office on those days and hear a Polish accent, that's her. A qualified nutritional therapist, Ula particularly enjoys the direct contact with patients — meeting them in person, offering support and seeing their progress. Although she now works mostly remotely, those personal connections remain what she values most about the role. She is here to help ensure everything runs smoothly and that patients feel well supported."

I now work alongside Dr Damien Downing who is a pioneer of integrative medicine and my favourite part of my role is supporting patients from their first consultation through to recovery, and seeing the difference our care makes."
