When Caitlin Ryan was a teenager in the 1960s, "lesbian" and "bisexual" weren't in the mainstream lexicon. The library was virtually the only place someone could go for accurate information about homosexuality. And when she came out to her own parents, they had no idea how to react. "I realized many, many years ago, more than 30 years ago, there had to be a better way," said Ryan, now 65. Since then, the San Francisco clinical social worker has spent her career understanding, researching and trying to improve health issues for lesbians, gays, bisexuals and transgender people across the nation.
