Rabbi Alex Chapper has been confirmed as Borehamwood and Elstree Synagogue's new senior minister after a members' vote.
He fills the vacancy caused by the departure of Rabbi Chaim Kanterovitz in November after a month of unexplained leave.
Rabbi Chapper joined the Hertforshire shul in 2017 as community minister with responsibility for continuing the development of its BES@Yavneh congregation.
He and his wife Eva have initiated a number of educational programmes for all ages.
Rabbi Chapper wants the synagogue to develop into "a truly seven-day-a-week community with a broad range of educational, social and cultural activities.
