Rabbi Shimon and Sarah Hecht moved to Park Slope in 1987 with two small children as emissaries of the Lubavitcher Rebbe to service the Jewish community in the Brownstone-Brooklyn area and to serve as the Rabbi of  Congregation B'nai Jacob.

Rabbi Hecht founded the Rabbinical Committee of Brownstone Brooklyn, and under his leadership, Judaism in Park Slope and its surrounding community areas of Brownstone Brooklyn have boomed. 

Rabbi Hecht was instrumental in installing the Park Slope Eruv that surrounds the neighborhood, and oversaaw the completion of The Park Slope Mikvah. Sarah and Rabbi Shimon opened and direct a leading and trend-setting Jewish preschool,  Chai Tots Preschool. Chai Tots has now grown to three locations - in Park Slope, Prospect Heights and Windsor Terrace - to help serve the growing demand for Jewish education.

Rabbi Shimon serves as the chaplain of Methodist Hospital, is a board member of National Committee for the Furtherance of Jewish Education, and co-directs the Rabbinical Committee of Brownstone Brooklyn.
