I ran over a dozen 2 week residential PDC's in Spain, with a strong focus on designing natural health as part of PC, to a very international audience 2002-2010, and have run PDCs over several months in Kent, largely as part of a staff and volunteer training programme with the Bay Trust - the latest in 2017 has been tied into staff work priorities for their design projects. I am on the LAND projects Advisory Group and the Education Working Group, and a joint coordinator of IPEN (International Permaculture Education Network) with Lachlan Mckensie - part of IPEN's focus is to collaborate internationally to develop new core courses and formats for permaculture educators to teach or facilitate. I did my PDC in 1994 (Stephen Nutt and Ann Morgan as tutors), and obtained my Diploma in 2001. I've written Eat More Raw (1st edition, Permanent Publications, 2005) and Eat More Raw Too (2nd edition, self-published, 2016-7) as a first book focused on an integrated approach to permaculture and natural health, addressing multiple inner and outer dimensions of health, not just nutrition ... all based on 'working with nature' and 'the problem is the solution'.
