He taught at the University of Texas at Galveston Medical Branch where he started a sex offender treatment program and ran the Rosenberg Gender Clinic.
He was openly gay.
In 1977 he was the defense psychologist at Fort Rucker. Alabama, where a young female soldier was accused of homosexuality for marrying a trans man, Kristian von Hoffburg.
After Reed Erickson closed the Erickson Educational Foundation in 1977, Walker and Zelda Suplee formed Janus Information Facility which carried on the work of EEF. Walker also became the founding president of the Harry Benjamin International Gender Dysphoria Association (HBIGDA now renamed WPATH) and wrote the first Standards of Care for transgender clients with input from other members of his committee.
Dr Walker was recommended by the syndicated newspaper agony aunt, Anne Landers, and that is how Sarah Weston, came to him for counseling early in her transition.
Paul Walker later moved to San Francisco. He died in the late ‘80s of AIDS complications.
The work of the Janus Information Facility was picked up by J2CP Information Services run by Jude Patton and Mary Elizabeth Clark.
