At Rambam Sephardi, Rabbi Jeff Berger is leading the drive to grow the community, supported by a dedicated and committed Board of Honorary Officers.
Originally from New York, Rabbi Berger, 52, is a product of the Montefiore Kollel, the programme set up by the Spanish and Portuguese community to train new central Orthodox rabbis for British Jewry. He is the first of its graduates to find a pulpit.
He had previously worked in electronic sales and marketing and met his wife Michie in Japan.
He has given up commerce and, apart from his new ministerial position, he will continue to teach - he delivers several lectures at Limmud.
An Ashkenazi in origin, he and his wife, who have two young children, used to attend the Spanish and Portuguese Synagogue in New York.
"We became enamoured of the music, the tradition and the 350-year old history," he said. "We want to continue that relationship."
