Rabbi Moshe Dovid Niederman's public service began with Jews trying to cross borders. In 1973, at Rabbi Yoel Teitelbaum's behest, he became the founding executive of Rav Tov. The organization met Jews leaving the Soviet Union in the transit cities of Vienna and Rome, arranged visas and travel, sustained families during the wait, and helped them begin again in the country of their choice.
When revolution and war endangered Iranian Jews, Rav Tov turned the same rescue machinery toward them. It helped obtain Austrian visas, brought refugees through Vienna, pursued asylum and resettlement, and arranged housing, medical care, schools, language instruction, and employment. Austria later honored Rabbi Niederman for more than three decades of leadership in rescuing Jews in peril.
The same instinct shaped his work in Williamsburg. As president and executive director of the United Jewish Organizations of Williamsburg and North Brooklyn, Rabbi Niederman works across social services, housing, education, public health, neighborhood safety, religious accommodation, and access to government.
His work shows one way a Satmar community participates in civic life: organizing its own institutions, cooperating with public authorities, expressing gratitude and loyalty to the country, and advocating lawfully for the needs of families and neighborhoods.
In testimony before New York City's Districting Commission, he described UJO as a central social-service agency representing more than 75,000 Yiddish-speaking residents of North Brooklyn. That scale turns translation, representation, and access into everyday communal responsibilities.
