Lisa Woll was named the first CEO of the Social Investor Forum, which consists of more than 500 portfolio managers, analysts, financial advisers and institutions such as banks, mutual fund companies, research companies, foundations and community investing institutions. Hiring Ms. Woll is part of the forum's "long-term plan to foster even more attention by institutional and other investors on the concept, practice and growth of socially responsible investing," , according to a statement from SIF. "The forum and its board have committed to strengthening service to our members and expanding the arena of social investing," Timothy Smith, president of the Social Investment Forum and president and senior vice president of Walden Asset Management, said in the statement. Ms. Woll was executive director of the International Women's Media Foundation; she left last year. She has no experience with an investment organization but the forum doesn't think that is necessary for the leadership role she will play, Mr. Smith said. Ms. Woll was not available for comment, said Patrick Mitchell, spokesman.
