Through Shavei Israel, Michael Freund is dedicated to restoring the Jewish identity of lost communities. Shavei Israel has worked with the crypto-Jews of Portugal and Spain, descendants of Jews who were forcibly converted during the Inquisition and facilitates aliyah for hidden Jews. The organization provides Jewish educational seminars, online resources, and community support to those seeking to return to their roots. In addition, Shavei Israel helps rebuild synagogues and mikvahs, while offering religious guidance and conversion processes in collaboration with Israeli authorities.
