One of the most iconoclastic is David Hartman of Jerusalem, whose support for pluralism has gained him serious backing in non-Orthodox streams and who has brought Soloveitchik's thinking to the non-Orthodox. The institution he founded, the Shalom Hartman Institute, is a home for serious thinkers from Orthodoxy, Conservative/Masorti, Reform and even secular scholars, and trains hundreds of Jewish community leaders annually. Rabbis Avi Weiss and Saul Berman, who represent liberal Modern Orthodox institutions such as Yeshivat Chovevei Torah and Edah, are somewhat further to the right of Irving Greenberg, Riskin and Hartman, but still very liberal in comparison to most Orthodox thinkers (Weiss has classified this approach as "Open Orthodoxy").
