Last week, 12 students from the Bergen County High School of Jewish Studies went to Charleston, S.C., to work on tikkun olam — to help repair the world. Miriam Pittinsky and Sarah Steinhardt, both of NCSY, and Fred Nagler, BCHSJS principal, accompanied them. Their activities included making breakfasts and lunches at the Ronald McDonald House to freeze for future use and helping at Habitat for Humanity’s Sea Island Homes. The students also learned about Charleston and its Jewish history. They ate dinner at the Dor Tikvah synagogue there.
