Jamison Green has spent his career fighting to make the healthcare industry a safer, more accessible place for transgender people. He gives the best explanation I've ever heard for why people feel threatened by gender nonconformity, talks about his work as the past president of the World Professional Association for Transgender Health (formerly the Harry Benjamin International Gender Dysphoria Association), and talks about coming into his bisexuality in his 50s. 
Jamison is the author of the very excellent memoir, Becoming A Visible Man.
