Phyllis Greenberger is President and CEO of the Society for Women’s Health Research, a national non-profit organization founded in 1990 to improve the health of women through research, education, and advocacy. Twenty years ago, most medical research focused on young, healthy, white men; the conventional thinking was that women were just “little men.” Today, thanks to the efforts of Phyllis and her organization, scientists recognize that women are different from men in many ways, and that research into drugs, diagnostic tools, and treatment must be tailored to their needs.
