Ani Pema Chödrön became a novice nun in 1974, in her mid-thirties, while studying with Lama Chime in London. His Holiness the Sixteenth Karmapa came to Scotland at that time, and Ani Pema received her ordination from him.

Pema first met her root guru, Chögyam Trungpa Rinpoche, in 1972 and studied with him from 1974 until his death in 1987. At the request of the Sixteenth Karmapa, she received the full bikshuni ordination in the Chinese lineage of Buddhism in 1981 in Hong Kong.

Ani Pema served as the director of Karma Dzong in Boulder, Colorado, until moving in 1984 to rural Cape Breton, Nova Scotia, to be the director of Gampo Abbey. She currently teaches in the United States and Canada and plans for an increased amount of time in solitary retreat under the guidance of Venerable Dzigar Kongtrul Rinpoche.

She is interested in helping to establish Tibetan Buddhist monasticism in the West, as well as continuing her work with Western Buddhists of all traditions, sharing ideas and teachings. Her nonprofit, the Pema Chödrön Foundation, was set up to assist in this purpose.
