Alan Atkisson: change agent

Alan Atkisson's sustainability service, from what I can gather thus far, incorporates SSD, some of what The Natural Step promotes..and focuses on process and organizational learning. He seems to provide lots of good process tools, found in the Accelerator toolkit. My housemate, Sean met him last week at a conference in Spain on sustainability and just finished his book, Believing Cassandra: An Optimist Looks at a Pessimist's World. I'm interested to explore his methods more.
