About The Guild

The Guild of Naturopathic Iridologists International has, since it’s inception in the 90’s, forged the successful integration of leading-edge Colleges and Courses within the UK, under the one umbrella organisation.

This has contributed to the Guild being able to provide the largest Register in the UK of professionally-qualified Iridologists, giving the public much needed protection from lacking sufficient training to reliably interpret signs in the irides.

In 1996, the ‘Secretary of State’ conferred ‘International’ status on the Guild, reflecting the contribution the Guild has made to worldwide scientific research into Iridology.

To learn more about the major role that Angela Bradbury and Peter Bradbury (RIP) played in the establishment of both Iridology and The Guild in the UK we are fortunate to have the history from Angela Bradbury herself.  This conversation was an ad-hoc, post Symposium chat  by Dr Isabelle Grote (www.foxburgh.co.uk).

Aims and Objectives

The Guild is the only ‘umbrella’ organisation for Iridologists in the UK.
It was created by the general consensus of professional Iridologists of many years standing, who wanted to see:

  • the protection of the public and prospective students established
  • the provision of post graduate training
  • the enforcement of a ‘Professional Code of Ethics’ and a ‘Constitution’


FULL MEMBERSHIP: – £135 Per Annum (£2.59 per week)

ASSOCIATE & OVERSEAS MEMBERSHIP:  £95 Per Annum (£1.82 per week)

LICENTIATE & STUDENT MEMBERSHIP:  £20 per Annum (£0.38 per Week)

The Guild was established to ensure that services of the highest professional standards are provided to members of the public. Student members are offered training of the highest integrity.
