He was married to Chava the daughter of Rabbi Shlomo Zalmina Zukerman of Rashkov.
In August, 1913 he left Russia for the United States. His leaving Europe was spurred by a series of events that found him at odds with the Russian government, including being arrested in order to be enlisted into the army. After being accused of stealing several Torah scrolls, he decide to move to America. He was in fact rescuing the scrolls that belonged to his father's synagogue from the house of the thief.
He opened a synagogue in the Lower East Side named Kahal Chasidim at 9 Attorney Street and later moved to Brooklyn at 142 21st Street.
