With Arthur Zajonc, McDermott is co-founder of The Owen Barfield Graduate School of Sunbridge College, is the founding chair of the board of Sophia Project (two homes in Oakland, California, for mothers and children at risk of homelessness), and has been chair of the board and president of many other institutions. He is a teacher and former board chair of the Rudolf Steiner Institute.
He has written a number of books, as well as essays published in scholarly journals and anthologies. His essays have appeared in International Philosophical Quarterly, Cross Currents, Journal of the American Academy of Religion, and Philosophy East and West.
Topics on which he has written or lectured include the evolution of consciousness, the spiritual mission of America, classic and modern spirituality and spiritual masters (East and West), Sri Aurobindo, and Rudolf Steiner and Anthroposophy.
McDermott's term as president of CIIS marked an extraordinary achievement. He was the first president in its history who filled out his terms of office without resigning or being dismissed (not counting the founder and first President, the Bengali scholar Dr. Haridas Chaudhuri, who expired in his office in 1975 while writing a student, shortly after teaching his last class in Modern Brain Research and Psychodynamics). McDermott was able to steer a very small and vulnerable institution away from the very edge of dissolution in bankruptcy into the thriving institution that it is today, nearly quadrupling its enrollment subsequent to McDermott's resignation.
