Rav Margareten, originally from Baltimore, Maryland, now lives and teaches in Cleveland, Ohio.  In addition to holding the post of Manahel Ruchni of Congregation Shomrei Shabbos and as a Rebbe at Mosdos Ohr HaTorah, the Rav gives two Daf HaYomi shiurim, a Tehilim Shiur, parsha droshos, and numerous speaking engagments locally and abroad.  In his spare time, the Rav learns with several chavrusahs. 

Rabbi Moshe Berger, a native Clevelander, also serves the community as acting president of Congregation Ahavas Yisroel.  Harbatzas Torah is his life career, serving as a Rebbe at Mosdos Ohr HaTorah.

As a graduate of the Telshe Yeshiva, Rabbi Berger brings to Kollel Dirshu the depths of knowledge afforded by learning torah directly from the mouths of gedolim.
