I am a registered Landscape Architect in North Carolina, USA, and have been teaching small-scale landscape design in the NC State University Department of Horticulture since 1979. I received my PDC from Chuck Marsh and Peter Bane, from a course taught at the Earthaven Community in Black Mountain, NC, in 1994. Since 1997, I have been teaching an Introduction to Permaculture at NC State University 'live', and have had it recorded and taught as a distance education course since 2003. Following David Holmgren's and the late Joe Polaischer's example of sharing all they know as open source information, given the worldwide environmental crisis that we face, I have posted the video tapes of my course lectures on the web; they can be seen at: http://mediasite.online.ncsu.edu/online/Catalog/pages/catalog.aspx?catalogId=f5a893e7-4b7c-4b79-80fd-52dcd1ced715. I also teach a landscape design studio course at NC State, and after students take both the introductory course and the landscape design studio, I will award them a certificate that leads to their PDC.

Although I have always taught landscape design as an ecologically based discipline, I became concerned, in 1988 while on a cross-continent bicycle trip, that there were almost no people out in the landscape observing what was happening. I looked around for a stronger statement, and eventually found permaculture.

My home landscape is a Pc model, with images of it seen on the cover of Toby Hemenway's "Gaia's Garden, 2nd Ed." The bulk of the permaculture designs that myself and my partners have completed are residential settings or urban food production gardens.
