Hogen Sensei

Hogen Sensei

Ron Hogen Green is a husband, father, grandfather, sports-enthusiast, retired podiatrist, and a lay teacher in the Mountains and Rivers Order. Hogen Sensei formally began practicing Zen in 1978 with Philip Kapleau Roshi, shortly after graduating medical school and entering private practice. In time, Hogen and his wife, Cindy Eiho Green, helped run the Denver Zen Center, an affiliate of Kapleau Roshi’s Rochester Zen Center. He attended his first retreat at Zen Mountain Monastery in 1988, and not long after began studying with Daido Roshi. In 1993, Hogen completed his training in the Kapleau Lineage and was designated a senior student in the Mountains and Rivers Order. He and Eiho left Denver in 1995 and entered full time residency at ZMM. At the Monastery, Hogen served as Director of Operations for Dharma Communications for 10 years and, in 2000, ordained as a monastic. 

In 2007, Hogen Sensei returned to lay life, spending time with family while continuing to play an active role in the MRO, its practice centers and affiliates. In 2016, he received dharma transmission from Shugen Roshi, becoming the first lay teacher in the Order. He served as co-director of the Zen Center of NYC for a number of years and currently divides his time between rural Pennsylvania and South Florida.

He is the author of numerous books, including The Eight Gates of Zen and The Zen of Creativity. Daido Roshi gave dharma transmission to Bonnie Myotai Treace, Geoffrey Shugen Arnold, and Konrad Ryushin Marchaj.
