The current flourishing center of Nadworna Hasidism in the Tel Aviv suburb of Bnei Brak was established by Rabbi Haim Mordechai (1903-1977) (Alfasi, 1:84), son of the Rabbi Ittamar Rosenbaum (1886-1973), known as "the Old Rabbi from Nadworna," a grandson of Rabbi Meir Rosenbaum (1852-1908) of Kretshnef (Crăciuneşti, Karàcsonfalva in Romania), a great-grandson of Rabbi Mordechai of Nadworna. The Bnei Brak center was created by Rabbi Haim Mordechai's son Rabbi Yaakov Issachar Ber (Alfasi, 1:87). Many other offspring of the dynasty have their courts in Israel and in America.
