The Avalon School of Colon Hydrotherapy in Glastonbury, Somerset is an independent training school specialising in small groups in order to maximise one-to-one tuition.

Our lead trainers have a combined experience in the health professions spanning over thirty years.

We train our students to become fully qualified and confident colon hydrotherapists using the Gravity Feed Closed System Method. This method was originally designed by Doctor Robert A. Wood in `1914. The Gravity Feed system is a gentle therapy that uses purified water to wash through the entire large intestinal tract, with the therapist present at all times.

Investing in this training opens the door to a flourishing market due to the increasing interest and concern of the general public regarding digestive health.

Our students can use their certificate to gain employment or to be self-employed following their training.

Our colonic school specialises in highly individualised training.
Our colonic courses are customised to guarantee good practice.

Fiona Bruce The Avalon School of Colon Hydrotherapy

Fiona Bruce:

Accredited Colon Hydrotherapist 2007
Accredited Teacher for Further Adult Education

Fiona has worked within the holistic therapeutic field for over thirty-five years. She qualified as a reflexologist in the 1980’s. She helped to establish the first and largest vegan restaurant in the UK which specialised in sugar free, wheat free and dairy free diets – run successfully from 1983 to 1995. From 1988 Fiona became a teacher in special diet cuisine both for the catering industry and for private individuals.

She has been the resident colon hydrotherapist at the Fisher King Centre (the longest standing residential cleansing retreat in the UK ) for over 12 years. This has led Fiona to develop a keen understanding in the way in which colonics aid digestive efficiency. She is passionately inspired by this line of therapeutic work.

Harriet Longman:

Registered Nurse, Diploma of Higher Education in Adult Nursing

Harriet has been a qualified nurse since 2004, with eleven years’ experience in critical care, which has given her an excellent understanding of the human body and the impact that disease has on us.

As part of Harriet’s role as a nurse she has mentored and taught many students and finds this a rewarding part of her job.

She also works in her family’s vegetarian and vegan whole food business.

Harriet’s extensive experience as a nurse, and now as a colon hydrotherapist, has been instrumental in developing her interest in diet and gut health.

The curriculum and accreditation will be assessment based. Evidence of competence and the development of performance will be measured using routine methods of monitoring and evaluation on a day to day basis.
