In 1979, Genthner met Korean monk and Zen teacher Seung Sahn during a retreat at the Providence Zen Center. In the early 1980s, he and several other individuals founded the Lexington Zen Center in his home, with retreats sometimes taking place at the homes of other practitioners. The group became affiliated with Seung Sahn's Kwan Um School of Zen, founded in July 1983. In 1986, he co-founded a Zen temple at Furnace Mountain with Seung Sahn. The temple, Kwan Se Um San Ji Sah (which means "Perceive World Sound High Ground Temple"), was completed in 1994. Also that year, Genthner/Dae Gak received Dharma transmission from Seung Sahn, and[2][3] founded the Cincinnati Zen Center.[4]
In 2000, Genthner was subject to disciplinary action following allegations by two patients of sexual misconduct and violations of patient confidentiality; while denying wrongdoing, he agreed to a suspension of one year, a fine, and one year of supervised probation after his license was reinstated.[5][6] Also in 2000, he left the Kwan Um School of Zen and began his own. He has since established groups in North America, Germany and England.[7][8][9] Genther, and the Furnace Mountain Zen Retreat Center was featured in the 2010 documentary film Zen Furnace[10] produced by Kentucky filmmaker Steven Middleton.
