Rabbi Dr. Marc Gellman is the Rabbi Emeritus of Temple Beth Torah in Melville, New York, where he was elected to the pulpit in 1981. He holds an earned doctorate in Philosophy from Northwestern University and was ordained as a Rabbi by the Hebrew Union College-Jewish Institute of Religion. Rabbi Gellman was the President of the New York Board of Rabbis during the attacks of 9/11.
He was twice selected as one of the 50 best Rabbis in America by Newsweek.  He also wrote a column, The Spiritual State, for Newsweek.com.  He presently writes a nationally syndicated weekly column, The God Squad, for Tribune Media Content.
Rabbi Gellman has delivered invited lectures at Princeton, Duke, Columbia, Lehigh, Jewish Theological Seminary, American Jewish University, and many other academic institutions.  He has served as adjunct faculty at Antioch College, Hebrew Union College, and Northwestern University.  He has lectured at Grand Rounds at Brigham and Women's Hospital of the Harvard Medical School; taught the medical staff of Mt. Sinai Hospital in symposia on medical ethics.  He was an invited participant at the World Economic Forum, Davos, Switzerland.
Rabbi Gellman has published in the Mt. Sinai Journal of Medicine; in Current Psychiatric Therapies: The Journal of the American Psychiatric Association; and in the journal of the United States Commission on Civil Rights.  He has written articles for First Things, Moment Magazine, Commentary, and other opinion journals and magazines.
Rabbi Gellman is the author of ten books for children and adults, many of them with his friend Monsignor Thomas Hartman including, Religion for Dummies.  Their book, Where Does God Live? was awarded the Christopher Award.  The HBO special based on their book, How Do You Spell God? was awarded the George Foster Peabody Award.
Father Tom and Rabbi Marc formed the "God Squad" in 1987 in order to convey through the media their mission statement, "We know enough about how we are different and not enough about how we are all the same."  For several years they served as the religion and ethics correspondents for ABC on Good Morning America.  They were the first clergy hired by a national network since Bishop Fulton J. Sheen. Telicare, the television station of the Diocese of Rockville Centre, syndicated their interfaith interview program, The God Squad, for over two decades. The readers of Newsday voted Rabbi Gellman and Father Hartman the most important activists and leaders on Long Island of the last century.  The movie, "Keeping the Faith" is based on their friendship.
A year after Father Tom's passing, Rabbi Gellman is planning to reprise The God Squad with Rev. Paul Crouch Jr. for Truli Media.
