After completing her Master’s in Public Policy at the University of Maryland, Rabbi Stein worked as a community organizer in Chicago. She then served as the Director of Jewish Student Life at the University of Washington in Seattle, and led their highly successful work in building engagement among not only students but faculty and professionals in the Seattle area.

Rabbi Emeritus Frank M. Waldorf started at Temple Sinai in 1974, teaching Torah in synagogue services, in adult education, and in the religious school. He was ordained on the Cincinnati Campus of Hebrew Union College-Jewish Institute of Religion in 1964. For four years he was an Army Chaplain including three years in Frankfurt, Germany. He came to Temple Sinai, looking for a smaller congregation where he could really get to know the congregants on an individual basis; and it would be very hard to find one member or even the occasional visitor to the synagogue who could honestly say that Rabbi Waldorf didn’t make the effort to get to know them. Rabbi Waldorf retired in 2004, but he is still engaged in the Sinai community as Rabbi Emeritus.
