## Biography

Leighton's father was a medical school professor and cancer researcher, his mother a high school French teacher and librarian. Leighton began his Zen practice in 1975 at the New York Zen Center, training under Kando Nakajima rōshi. He studied at Columbia University, where he obtained a bachelor's degree in East Asian studies. Leighton worked as a television and film editor in New York City, and then San Francisco.
In 1978, he moved to California and eventually became a resident at San Francisco Zen Center, where he worked at Tassajara Bakery and other of Zen Center's businesses. In subsequent years, Leighton practiced in residence at all of the San Francisco Zen Center facilities, including Green Gulch Farm Zen Center and Tassajara Zen Mountain Center. In 1986, Leighton was ordained as a priest by Reb Anderson in the latter's first ordination ceremony. In 1990 Leighton served as shuso (head monk) for the Spring practice period at Tassajara monastery under Zenkei Blanche Hartman as her first shuso.
Leighton lived in Japan from 1990–1992, translating Dōgen texts with Shōhaku Okumura and training under various masters. In 1994, Leighton founded the Mountain Source Sangha in Bolinas, San Rafael, and San Francisco, California (of which Ancient Dragon Zen Gate is a sister temple).
In 2000, Leighton received shihō, or Dharma transmission, from Reb Anderson.
He taught for four years at Loyola University Chicago and has taught since 1994 at the Institute of Buddhist Studies, part of the Berkeley Graduate Theological Union, from which Leighton has a Ph.D. degree.
Leighton has been involved in many interfaith dialogue programs, including conducting Buddhist–Christian dialogue workshops. He has long been active in various Engaged Buddhist programs for social justice, including Environmental and Peace activism. Leighton's peace activism goes back to dedicated anti-Vietnam War work in high school, and he was then as a College freshman arrested as part of the 1968 week-long building occupation at Columbia University protesting the War and racism.
In 2007 Leighton relocated to Chicago to serve full-time as Guiding Dharma Teacher for Ancient Dragon Zen Gate, which he had founded with students there a few years before. In 2008 Leighton performed Zuisse ceremonies at Eiheiji and Sōjiji temples in Japan to be recognized as a Dharma teacher by the Japanese Sōtō School. In 2019 Leighton completed Dharma transmission ceremonies at Ancient Dragon Zen Gate for his Dharma heirs Nyozan Eric Shutt and Eishin Nancy Easton.
