The Jewish Orthodox synagogue of Shevet Achim is one of two Jewish religious congregations on Mercer Island. The Orthodox Jewish faith follows both the Ashkenazic and Sephardic custom. Rabbi Yechezkel Kornfeld leads the celebration of the Sabbath (Shabbat) and holiday services in the sanctuary of Northwest Yeshiva High School. Following morning services, a Kiddush blessing is held and food and drink are shared. Visitors are welcome.
