I did an MA at the ISE back in early ’90’s and have been on faculty since 2000. Situated in lovely Plainfield, VT the Institute is well worth investigating. It has changed (read: contracted) significantly over the past few years, but we still offer an MA program through Prescott College in Arizona as well as a series of seminars, workshops and events based around an ecological and socially reconstructive pedagogy and philosophy.  It’s a good place with compelling history and body of work.
