About the London Clinical Team

We have taken great care to employ caring and compassionate healthcare specialists who are friendly and excellent at communicating with patients. We share a passion for being at the frontier of the emerging field of technology-based medicine and solving health challenges.

For Optimal Health Assessments and Re-Tests you will see a Senior Clinician (SC). These practitioners will be naturopathic or medical doctors or senior nurses.

For other Assessments and Treatments you will be cared for by a Clinician or a Patient Care Assistant (PCA). These Patient Care Assistants will be therapists, nurses or health care workers..

Therapies and Services are offered by experts in their field who all share the same optimal healthcare vision.
