Congregation Mount Sinai believes that a synagogue should welcome all as members of one family. We are a caring and sharing community that seeks to accommodate the diverse spiritual needs of the Jewish community and those who are interested in Jewish life. We are proud that our sacred space is a place where unity of spirit and diversity of thought support each other. Congregation Mount Sinai is an independent egalitarian synagogue that warmly welcomes people of all ages, backgrounds, affiliations, family structures, and sexual orientations. Interfaith families, those with little or extensive Jewish backgrounds, and Jews by choice are all welcome to join us.
