It is the intent and purpose of the General Council to serve as a connection to the incarnation of anthroposophy in our time.

Helen-Ann Ireland,
Council Chair

Helen-Ann began exploring spiritual ideas in high school when she wrote a paper on Buddha and Christ. After meandering through some Eastern pathways and traveling, she met anthroposophy in Australia when she became interested in educating and raising children in a wholistic way. Through her work as a class teacher in Honolulu and then Pine Hill in New Hampshire, she continued to study and deepen her interest in Steiner’s works. For seven years, she was the Vice-Chair of the Hawai’ian Society and became a member of the First Class there in 1992. After graduating her second class of children at Pine Hill in 2009, she pursued doctoral studies at UMass Amherst and co-authored a book Assessment for Learning in Waldorf Classrooms. Having been conferred her title in May 2018, she is currently working as a post doc fellow at UMass Amherst and will continue as a lecturer coordinating the Elementary Educator Master’s Degree program and teaching undergraduates about human development. At the same time she entered her doctoral program, she was appointed as a reader for the First Class, School of Spiritual Science, in February 2011 for Wilton, NH.

Hazel Archer Ginsberg,

Having grown up in the Heart-Land, Hazel took her heart to San Francisco at the tender age of 16 to study Philosophy and Comparative Religion (with a minor in Women’s Studies). She met Rudolf Steiner’s Spiritual Science through Owen Barfield, and her work with the Societas Rosicruciana in America (S.R.I.A). Landing in New York, she began applying her Midwest work ethic, and her eclectic blend of teachings, building community with disenfranchised youth for the Homesteading Movement on the Lower East Side, all the while creating experiential theater, and playing music in various original Bands. Hazel is a biodynamic ‘Merry Prepstir’, a meditant, essayist, lecturer, poet, and a Trans-denominational Minister - creating custom ceremonies for all occasions. She has been founder and facilitator for many initiatives over the years. Inspired by Rudolf Steiner’s original Calendar of the Soul commemorating feast days, and birth and death days of important individualities, Hazel connects the seasonal round with human karma, and great historical events in her Reverse Ritual blog: Understanding Anthroposophy through the Rhythms of the Year, and the ‘I Think Speech’ podcast. Hazel is the Cultural Events and Festivals Coordinator for the Chicago Rudolf Steiner Branch and a member of the Central Regional Council. She is a member of the First Class of the School of Spiritual Science, and of the Esoteric Youth Circle. Hazel offers anthroposophical lecture presentations, workshops and festivals around the world.


Christine Burke,
Western Region

Before completing a Waldorf Teacher training through Rudolf Steiner College (San Francisco) under the guidance of Dorit Winter, Christine earned a BA in Linguistics from UC Santa Barbara. Christine taught in Waldorf schools in California and Sweden before training in Formative Speech (Sprachgestaltung) and Drama at Artemis School of Speech and Drama (England) with Christopher Garvey. She earned a Masters in Communication Studies with an emphasis in Rhetoric (read: classical studies) and Performance at a local university, where she was able to bridge many of her studies and projects to anthroposophical initiatives and concepts.

Currently, Christine teaches Communication Studies at her local college and at a nearby university and travels to conferences, Waldorf schools, teacher trainings, and Christian Communities throughout the world to teach speech and drama and lead groups in a variety of themes. Christine manages the “for social benefit” company she founded in Ventura, California called Caffrodite Community Collective, which opened just before the corona virus changed our ways of gathering.  She leads meditations online and volunteers on local boards to continue her passion for fostering the art of community, exploring the many paths of this “art of the future” as Rudolf Steiner called it.  She is part of the collegium of the Social Sciences Section of the School for Spiritual Science in North America and is the Western Regional Council’s representative on the General Council.

Christine spends the remaining hours of her life balancing the loving duties that come with being the companion of a beautiful chocolate cocker spaniel and performing in street theater, community theater, a variety of activist performances and the life-infused, life-long learning of coming to know herself.


Rudolf Steiner sculpting the "representative of humanity"

Position Statement on Diversity

The Anthroposophical Society in America [US] is committed to honoring and supporting every human being in fulfilling their potential. Individuals engaged in continuing self-development and with interest in one another are the necessary foundation for strong, healthy communities of all kinds, for the global ecology that we carry together for the benefit of all.

The Anthroposophical Society in America [US] does not condone or support any activities of individuals or organizations that deny or denigrate the dignity and humanity of any human being or group of human beings.

The founder of anthroposophy, Rudolf Steiner (1861-1925), was a spiritual researcher of human origins and the evolution of consciousness from a Western perspective. He developed his insights into many practical applications for the benefit of humanity. He addressed questions of individuality, race, ethics, and religions in his talks and writings in the early 20th century.

We acknowledge and understand that readers today will likely find some of these lectures and passages that characterize race and other group identities to be deeply offensive. The negative views of race and religions implied in these passages are unacceptable in any contemporary context and do not inform any aspect of the work of the Anthroposophical Society in America [US].

We explicitly reject any theory that might be construed to be part of Rudolf Steiner’s work that characterizes or judges any human being as superior or inferior based on racial, gender, ethnic, religious, or other group identity.

Throughout his life, Steiner spoke about the growing social and spiritual importance of overcoming racism for the health of communities and future humanity. A very clear statement of this view is in Lecture I of his series The Universal Human (1909): its fundamental nature, the anthroposophical movement . . . must cast aside the division into races. It must seek to unite people of all races and nations, and to bridge the divisions and differences between various groups of people. The old point of view of race has a physical character, but what will prevail in the future will have a more spiritual character.

As a leadership group for the Anthroposophical Society in America [US], the General Council affirms and commits to the practice of a more just and equitable human future and to encouraging such practices in all anthroposophical organizations and activities.

Membership in the Anthroposophical Society is open to everyone who sees the value of anthroposophy without regard to gender, national origin, race, ethnicity, sexual orientation, age, or religion. In addition, the Society encourages a wide range of artistic, scientific, and economic perspectives and practices. The US Society is part of the worldwide General Anthroposophical Society centered in Dornach, Switzerland. More information about the Society can be found at
