Turning Mourning into Mission is not a slogan for the Goodman family; it is a lived commitment forged in loss. After the death of Yosef Goodman while serving in the Israeli army, his family confronted a question that haunts so many bereaved families: what comes after the shiva ends and the world moves on. Their answer became Just One Simcha, a quiet but powerful movement dedicated to ensuring that children who have lost a parent still experience the dignity, joy, and communal embrace of a bar mitzvah. In a country where grief is widespread but often carried privately, the Goodmans chose to transform personal mourning into public responsibility, insisting that remembrance must be active, not symbolic. Each bar mitzvah is more than a ceremony; it is a declaration that loss does not erase belonging, and that even in the shadow of tragedy, joy can be rebuilt—one simcha at a time.
