Rabbi Hoffman has written or edited over forty books, including My People's Prayer Book (Jewish Lights Publishing), a ten-volume edition of the Siddur with modern commentaries, which was named a National Jewish Book Award winner for 2007. His Rethinking Synagogues: A New Vocabulary for Congregational Life (Jewish Lights Publishing) and his Art of Public Prayer (Skylight Paths) are widely used by churches and synagogues as guides to organizational visioning and liturgical renewal. In 2011, he received a second National Jewish Book Award for co-authoring Sacred Strategies: Transforming Synagogues from Functional to Visionary (Alban Institute).
His articles, both popular and scholarly, have appeared in eight languages and four continents, and include contributions to such encyclopedias as The Macmillan Encyclopedia of Religion, The Oxford Dictionary of Religion, The Encyclopedia of Judaism and The Encyclopedia of Religion in America. He syndicates a regular column which appears, among other places, in The Jewish Week and The Jewish Times; and writes a blog entitled "Life and a Little Liturgy."
For many years, Rabbi Hoffman served as visiting professor of the University of Notre Dame, and has lectured at such places as the Jewish Theological Seminary of America, the University of Southern California, and the Yale Divinity School.
In 1990, Dr. Hoffman was selected by the United States Navy as a member of a three-person design team, charged with developing a continuing education course on worship for chaplains. He is a past-president of the North American Academy of Liturgy, the professional and academic organization for liturgists, and in January 2004, received that organization's annual Berakhah Award, for outstanding lifetime contributions to his field.
In 1994, he co-founded "Synagogue 2000," a trans-denominational project to envision the ideal synagogue "as moral and spiritual center" for the 21st century. As Synagogue 3000, it has launched Next Dor, a national initiative to engage the next generation through a relational approach featuring strong communities with transformed synagogues at their center.
