As Rabbi Joshua Berkowitz told the New York Times upon the Agudas Achim's 100-year anniversary, the congregation had only five rabbis over the course of its first century, contributing to its longevity and rootedness. Synagogue president Leon Chameides concurred that rabbinic leadership [is] the glue that has held the synagogue together.
The congregation's first rabbi, Isaac S. Hurewitz, served from 1893 until 1935, while simultaneously working as a kosher butcher. A synagogue on Market Street opened in 1903, under his leadership. He was still in charge in 1928, when the new Greenfield Street synagogue was built.
