Rabbi Ari is a member of all three liberal rabbinical associations. He was a rabbi and scholar-in-residence at independent liberal synagogue Etz Chayim for 19 years, and before that, the Hillel Director (Jewish campus minister) at Stanford University for 21 years. At Stanford he was the founder and president of the Stanford Associated Ministries which brought all the religious efforts together for common purpose and understanding. He worked with the Deans of the Chapel to bring interfaith panels to dormitories and departments. He had honed his interfaith skills growing up in a large extended family of Jews and Christians, and refined it through formal years of work at his rabbinical school, and in a yearlong interfaith apprenticeship seminar in Washington D.C. the year before his ordination as a rabbi. Part of this position involved staffing the meetings and commissions of the InterFaith Commission of Greater Washington D.C., which handled national religious policy and lobbying.
He and his wife Joy reside in Palo Alto, CA, and have four grown amazing daughters.
