About Us

Dr David Mickel MBChB MRCGP- Founder and Director

David qualified as a Medical Doctor in 1992 before going on to specialise in General Practice in 1996. He developed an interest in CFS/ME and Fibromyalgia during this time and became frustrated by the lack of success of conventional and alternative treatments for the conditions. He spent a number of years researching and experimenting with a variety of approaches and methods until he finally developed the process of treatment now known as Mickel Therapy®. He founded the organisation Mickel Health Initiatives Ltd with the aim of offering high quality treatment and education in the theories and processes that he and the team have developed and evolved over recent years. Dr Mickel worked part-time in General Practice before developing his role as an Emergency Doctor in his local hospital A&E department. He is now available to provide Mickel Therapy by phone and e-mail.

He travels internationally to provide training, seminars and workshops.

Brydie J Thatcher – Managing Director

Brydie studied Rural Business Management at Aberdeen University and the Scottish Agricultural College. She went onto embark on an early career as Agricultural Diversification Advisor and Equine Business owner before transferring to the NHS in her mid twenties. Brydie has now worked within the NHS for over twenty years as Operational and Clinical Service Manager. During this time she has worked closely with multiple disciplinary teams, clinicians, nursing and allied health professionals to deliver and develop high quality, patient centred services across a broad directorate of specialties including Emergency Medicine, General Medicine, High Dependency and GastroenterologyBrydie has also worked for the Scottish Government, Health Improvement Scotland as an advisor and inspector within the Joint Advisory Group for the  Gatroenterology Diagnostic Collaborative.

As the daughter of a Psycho Therapist she became aware of Mickel Therapy many years ago when her father sought out Dr Mickel to understand more about his therapy which had gained strong local recognition, indeed it had become something of a phenomenon. Whilst this initial contact gave her some understanding of Mickel Therapy it was not until many years later when she found herself as Manager of the Emergency Department in which Dr Mickel worked that she got to know about both him and his highly acclaimed therapy. Brydie was inspired and amazed by the incredibly restorative impact Mickel Therapy reportedly has had on so many lives, returning clients both to themselves and their family and friends. Brydie was particularly inspired by the transition and empowerment of energy disorder sufferers from clients to practitioners themselves.  Brydie and David now share their lives and live together in rural Moray with a selection of children and dogs.

Brydie became Managing Director in 2019 with the clear and simple objective of expanding the company to provide opportunity for practitioners to make a positive difference to as many lives as possible.

Clare Caldwell – Clinical Director

Clare Caldwell has extensive experience as an Advanced Mickel Practitioner. She also works as a distance practitioner providing the therapy by phone email and skype.

Clare Caldwell lives in the Highlands of Scotland.

It was the nature of the area she covers that led her to become a distance practitioner. So many of the clients she saw were unable to travel the huge distances to Inverness from the north of Scotland and the Islands that she quickly realised there was a need to provide the therapy in this way. She also worked for many years as a volunteer on a telephone helpline which gave her the unique experience to prepare her to provide the therapy in this way.

Clare has found that the therapy is just as successful by phone and email as in face to face sessions. Many clients even prefer the therapy delivered in this way

Clare qualified in Institutional Management in 1979 at the University of North London and worked in NHS management for many years. Her final job in management was as a Hospital General Manager in a London teaching hospital.

Clare experienced the symptoms of ME for 15 years. She was severely debilitated and was mostly wheelchair and bedbound during that time. She was always convinced there must be a cure and tried many therapies with little relief until she happened upon Mickel in 2004. She returned to symptom free health in just seven sessions.

Since then she has worked hard to raise awareness of the therapy. Clare is the clinical advisor and as head of training assists Dr David Mickel in the training of new Mickel Practitioners.

Clare is part of the management team where she is using her extensive experience of the therapy and her previous management skills and knowledge to assist the team. Their aim is to raise awareness and promote research into Mickel Therapy and the disorders it can help.

She works with people from many parts of the world and is interested in exploring how our cultural conditioning and expectations affects our health and the way we respond to the symptoms of illness.

Leisa Zakeri  – Supervisor, Practitioner and Trainer.

Leisa has a BA Hons in Psychology, an MSc in Occupational Psychology and
is registered as a Practitioner in Training with the British Psychological
Society and aims to become a Chartered Occupational Psychologist.

After completing her studies, Leisa went on to build a career in London
in the supported employment field working in the public, private and
charity sector and has gained a wealth of experience in working with the
long term unemployed, specialising in both brain injury and mental health.

While working in London Leisa started to experience symptoms of CFS/ME
which became so severe she had to move home to Scotland and stop working
for a prolonged period of time.  Leisa tried many therapies before coming
across Mickel Therapy, was treated by Dr Mickel, fully recovered and then
decided to train as a practitioner to help others do the same.  Due to
personal experience of the illness coupled with her professional
background, Leisa feels she has a lot to offer clients and is very gentle
and empathetic in her approach.

Leisa is currently based in Inverness and offers face to face sessions with clients locally.  She is also able to offer treatment over skype/telephone and email for long
distance clients and is currently working successfully with clients internationally. Leisa assists in the training of new Mickel Therapy Practitioners and acts as a Supervisor

 Angela Wilson – Professional Development Adviser

Before M.E and then Mickel Therapy radically changed the course of her life, Angela had spent eighteen years working in television for the BBC.   For the first five she was a Production Secretary and then Production Assistant before moving into the sharp end of the business as a Vision Mixer.

In 1987 M.E brought this much loved life to a grinding halt and she spent the next nineteen years very ill indeed and with no meaningful life whatsoever.   In her quest for health she tried at least a dozen different ‘cures’.   These ranged from the more conventional alternative therapies (acupuncture, homoeopathy) to what some might regard as the downright whacky (hyperbaric oxygen, enzyme potentiated desensitisation).   But extremely ill she remained.

Then along came Mickel Therapy, and just eight sessions and three or four months was all it took to put an end to nineteen years of non-life.   To her astonishment Angela was now symptom free.   She went on to train as a Mickel Therapist in 2008, since when it has been her privilege, joy and passion to be able to help others turn their lives around and reclaim their health, just as she had done before them.

Angela practises both face to face in South Manchester and, increasingly, at distance via Skype.   In addition to her own practice she provides supervisory support to other therapists.
