From 1978 to 1983 she lived at Zen Center of Los Angeles, studying with Maezumi Roshi and directing the Zen Center’s non-profit Medical Clinic. She finished formal koan study in 1983 and she was given Dharma transmission (authorization to teach) that same year. Following the death of Maezumi Roshi in 1995 she continued her training with Shodo Harada, Roshi, a Rinzai Zen teacher and the abbot of Sogen-ji monastery in Japan.
