Last year I attended, in person, Darren Doherty's REX10NY training in Essex, NY. If was phenomenal!
Darren has combined Holistic Management, Keyline Design and Permaculture Design to into an integrated practice developed through his 2000 farm design consultations around the world. This course also factors in farm economics where Permaculture and PDC's generally do not.
Many good practitioners and teachers of Permaculture and the Regrarians Platform I know personally have been added as support staff.
