Rabbi Shlomo Margolis' illustrious past led him to the personalities of R' Chaim Ozer Grozensky zt"l, R' Elchonon Wasserman zt"l as well as R' Elazar Menachem Man Shach zt"l. He assisted the Roshei HaYeshiva in Novardhok, as well as serving the community in Boston, before moving to his current residence in Bnei Brak.
His writings are down-to-earth, mussar based Divrei Torah, culled from the luminaries of the past and present generations.
