Jack Duffy Roshi





JACK DUFFY ROSHI was given permission to teach by Robert Aitken Rōshi in January 1992, followed by independent teaching status and the title of Rōshi in the formal Transmission Ceremony five years later. Jack became a student of Aitken Rōshi in 1981 and also has studied with Joan Rieck and Thich Nhat Hanh. He brings his roles of spouse, father, and psychotherapist, as well as years of endangered species work and wilderness wanderings, to his teaching.

MADELON YAMANE BOLLING was appointed Zen teacher in 2012, and she is an apprentice to Jack Duffy Roshi. In long search for a spiritual home she entered monastic life in another tradition in 1968, returning to lay life as a professional musician in 1974.  In 1983 she began practicing Zen with another group, eventually serving as dharma teacher there until 1993 when she began sitting with Three Treasures. A clinical psychologist in private practice since 2003, she also bears the sensibilities of past work as a landscape gardener, master composter and Permaculture designer.

LEE SHIELDS began practicing in a monastic setting during the early 1970s, sitting with several Zen teachers. In 1988, he joined Three Treasures Sangha and began studying with Joan Rieck.  Jack Duffy Roshi became his teacher in 1992, and appointed him apprentice teacher in 2012.  As a lay practitioner, Lee balances marriage, family, and work as an engineering consultant and now as a psychotherapist. Of importance to him is the interface of traditional Zen training with the daily, mundane, and extraordinary experiences of life.





ROBERT BAKER AITKEN was born in Philadelphia, but grew up largely in Hawaii, having moved to Honolulu at the age of five with his parents and younger brother, when his father, an anthropologist, joined the ethnology field staff of the Bishop Museum.

Working as a civilian in Guam, he was captured at the outbreak of World War II in the Pacific. His fortuitous introduction to Zen came through a fellow internee R.H. Blyth (the British writer) during their ensuing years of internment in Japan.


After his release, Aitken Rōshi resumed his interrupted college studies at the University of Hawaii, where he graduated in 1947 with a bachelor’s degree in English literature. He received a master’s degree in Japanese studies in 1950. His master’s thesis, which concerned Zen’s influence on the great haiku poet Bashō, later became the basis of his first book, A Zen Wave.
