Ayya Santussika, in residence at Karuna Buddhist Vihara (Compassion Monastery), spent five years as an anagarika (eight-precept nun), then ordained as a samaneri (ten-precept nun) in 2010 and as a bhikkhuni (311 rules) in 2012 at Dharma Vijaya Buddhist Vihara in Los Angeles.

Ayya Santussika was born in Illinos in 1954 and grew up on a farm in Indiana. While being a single mother, she received BS and MS degrees in computer science and moved with her two children to the San Francisco Bay Area. She worked as a software designer and developer for fifteen years. Her search for deeper meaning and ways to be of service led her to train as an interfaith minister in a four-year seminary program that culminated in an Masters of Divinity degree and a brief period of practice as a minister before ordaining as a Buddhist nun. She is currently serving on the Board of Directors for Buddhist Global Relief.
