Jamison Green is widely recognized as one of the most accomplished contributors to the contemporary transgender movement for health, civil rights, social safety, dignity and respect for gender-variant people. He is a writer and educator, born (1948) and raised in Oakland, California. He holds both a BA and MFA in English from the University of Oregon. He is currently enrolled at Manchester Metropolitan University in England, where he is completing his doctoral dissertation on the law impacting transsexualism.

In 1994, he authored the landmark document "Report on Discrimination Against Transgendered People" for the San Francisco Human Rights Commission, which served as the foundation for the establishment of protective legislation in the City and County of San Francisco, and specified much of the agenda for the contemporary transgender movement. He developed the curriculum on transgender sensitivity training that has been used since 1995 at the San Francisco Police Academy, and which has been adapted for use in other cities. The Advocate magazine named him one of "our best and brightest activists" (1999); he was the first transsexual man so named.

Jamison is in demand as a speaker around the world. He is a popular guest lecturer at many colleges and universities, and at professional meetings in such disciplines as law, psychology, medicine, theology, and corporate/business management. He has keynoted numerous conferences and events around the country, including San Francisco Pride, San Diego Pride, and Portland (OR) Pride, and symposia such as "Sex Change at Stanford," Stanford University (2000) and the TransFabulous Festival of the Arts. He has appeared in a dozen educational films, including the award-winning "You Don't Know Dick." He has appeared in person and on radio and television to educate about transsexualism in the USA, Canada, Great Britain, France, Germany, Sweden, Norway, Serbia, Israel, Turkey, Columbia, Australia, Taiwan, and Japan. He has also worked with mental health professionals to develop training programs for continuing professional education seminars offered through JFK University and professional groups.

His writing has appeared regularly in his featured column on PlanetOut.com and in such anthologies as The Transgender Studies Reader (edited by Stryker and Whittle, Routledge, NY, 2006) and Unseen Genders: beyond the binaries (edited by Haynes and McKenna, Peter Lang Publishing, NY, 2001). His own book, Becoming a Visible Man (Vanderbilt University Press, 2004) won the Silvia Rivera Prize for Best Book in Transgender Studies (2005) and was a Lambda Literary Award Finalist.

He began his transition from female to male in 1988 while employed as an engineering group manager at Sun Microsystems, Inc. He led FTM International, Inc. from March 1991 until August 1999, and he presently serves on the board of directors of the World Professional Association for Transgender Health, and several other nonprofit educational organizations. He has received awards of distinction from all of the largest, most established transgender organizations in the U.S., and was the first transman to receive the Distinguished Service Award (May 2009) from the Association of Gay & Lesbian Psychiatrists for his contributions to LGBT mental health.
