I received my Permaculture Design Certificate (PDC) in November of 2017. I took the year-long PDC from Geoff Lawton online. It was a massively comprehensive course. As part of my studies, I also completed listening to the 80-hour 1983 Bill Mollison PDC on MP3, and also read the entire 559 page Permaculture: A Designers’ Manual.
I am currently working on my first two demonstration sites. One is a residence and another a 72-acre parcel in the drylands of northwestern Utah.
