Clinic Team

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.

Adrian Dickinson

Analytical Energy Psychotherapist

Adrian has been in private practice since 1996. He has worked as a supervisor and tutor at Westminster Pastoral Foundation (WPF) and as an assessment psychotherapist at the student counselling service at UCL.

Since 2007 he has also trained in various modalities of Energy Psychology which all derive from the concept that distress and dysfunction, whether physical, emotional or mental, are encoded within the body-mind system and can be de-coded and dissipated by acupoint stimulation and other methods. This is particularly effective in treating disorders involving trauma, such as anxiety and panic attacks, and in transforming negative beliefs about the self and the world that are also often the result of traumatic events. Energy Psychology is fully complementary to the intrinsic self regulating approach of Health Optimising.
