The previous Admor of Savran was Rebbe Yissakhar Dov Hager of Har Nof, Jerusalem (died in 2013).
He was the son in law of Rabbi Avraham Leib Klein who served as the Mashgiach of the Rizhner Yeshiva in Jerusalem.
The Rebbe lived few years in Ashdod but used to come to Jerusalem every Shabbat and Yom Tov to conduct prayer services and Tishim in the Beis Medrash of his late father.
He often visited throughout the week to deliver Torah classes as well as conduct meeting where he councils individuals.
Among other hasidic melodies specific to Savran, Rebbe Moshe Zvi Giterman composed a very inspiring version of "B'nei heicholo" that is traditionally sung at Seudah Shlishit.
