Born in the Williamsburg section of New York into a family with a long rabbinical tradition, Rav Berg later was himself ordained, and dedicated himself to the study of Kabbalah. He and his wife Karen opened the doors of The Kabbalah Centre in 1971 to all persons interested in achieving self-improvement through spiritual realization. Under the Rav's leadership, KCI has become a vibrant international organization with more than 20 centers and 50 study groups.
