A psychologist and educator, Dr. Ruben has given courses at the secondary and college levels on the recognition of gender inequalities. She has created courses for teachers and counselors to help them recognize gender inequalities in schools. She promotes women through her two organizations, “Margaret for President” and “Women are Wonderful, Inc.” “Women are Wonderful, Inc.” reaches adults through seminars, magazine and newspaper articles, speeches, and a website. “Margaret for President” clubs promote female leadership in schools. Dr. Ruben has made an impact that has been felt nationally. She fought and won Wal-Mart’s withdrawal from sale of her “Someday a Woman will be President” T-shirt, which features Margaret of the Dennis the Menace comic strip. This T-shirt has since been distributed nationally to students’ and women’s groups.
