Rav Aharon Olshin, the eldest son of Rav Yeruchem and the next in line to become a BMG rosh yeshiva, delivered his first Shiur Klali in the yeshiva today. Rav Aharon is also the son-in-law of Novominsk Rosh Yeshiva Rav Yossel Mermelstein shlit”a. BMG officials told Lakewood Alerts that although this shiur is a historic first, there are no plans to install Rav Aharon as a full-time member of BMG’s hanhala at this time. Other children and sons-in-law of BMG roshei yeshiva also delivered their own shiur following Rav Aharon’s. The BMG roshei yeshiva were in attendance for all of them.
