Rabbi Ovadiah Dubin was a student of his father, Mr. Yisroel Eliyahu Dubin, Rabbi Yakov Moshe Shurkin, Rabbi Yitzchok Hutner and Rabbi Avraham Pam, OBM. In his early twenties he was sent by Rabbi Hutner to begin teaching a class, and has been teaching all areas of Torah ever since, for over 75 years. His complete mastery of the text material and commentaries is breathtaking, and his ability to explain it by reference to the range of human nature - from history to current events - makes the text material come to life.
