Meet the Team

Cressida Elias and Susan Cachay

At Halr Analysis UK we use Analytical Research Laboratories, USA (ARL) for the hair mineral analysis testing and use the science of Dr Eck on minerals and their ratios to devise personal nutritional balancing programmes for clients.  We incorporate the work of Dr Lawrence Wilson who worked with Dr Eck for many years and continued his work by adding some improvements and detox suggestions.   Dr Wilson's brilliant additions to Dr Eck's programmes speed up the healing process but we make sure Dr Eck's science is not compromised.  In addition Cressida and Susan bring over 22 years combined nutritional experience to the programmes that are helping people regain their energy and healing ability. 


We have the full support of Doug and Ken Eck at ARL who give us feedback when appropriate for any hair analysis test.

Dr Lawrence Wilson biography 

grew up in New York state.  He has a bachelors of science degree from the Massachusetts Institute of Technology and a medical degree from the Centro De Estudios Universitarios Xochicalco, Ensenada, Mexico.

For over 40 years he has worked as a nutrition consultant refining the science of nutritional balancing.  He has reviewed over 35,000 hair mineral analyses.

He learned some basics from Dr. Paul C. Eck, a brilliant biochemist and founder of Analytical Research Laboratories for whom he worked for 14 years..  He has expanded the work since Dr. Eck passed away adding procedures that greatly enhance the detoxification of toxic metals and discovering newer hair patterns that are emerging today in our ever increasing toxic world.

We use many of Dr Wilson's additions.  

Dr Heather Kneale, Doctorates in Naturopathy, PhD in Metaphysical Humanistic Science specializing in Holistic Life Coaching.  We sometimes review tests with Dr Kneale.
