I did both the Permaculture Design Course here and the course on starting and sustaining intentional communities. OAEC is the perfect setting for these courses and the teachers are wonderful.
The food is incredible, grown on the property in soil that has been cultivated biodynamically for 30 years! The property is the closest to paradise on earth that I've found, incredibly beautiful and diverse, the accommodations are lovely and I would stay here forever if I could. The teachers are knowledgeable beyond compare - leaders in their fields with decades of experience.
