Paul A. Walker (psychologist)

Walker died in November 1991 complications from HIV/AIDS.

Walker started his private practice in the early 1980s, moved his office to 1952 Union Street, San Francisco, California, treating transgender patients, including those with gender dysphoria, who identify with a gender they were not assigned at birth. Walker later came out as openly gay, and he lived on Castro Street, the most popular district in San Francisco for the gay community, as he continued his practice to specially help patients to seek sex reassignment surgery (SRS) almost until his death. Walker typically diagnosed his patients with "anxiety" to keep their identities private and confidential between the doctor and patient until beginning the real life test, now called socially transitioning. Before SRS, a year of living in the gender role that is congruent with the true gender identity is required.

Walker graduated with a doctorate in social psychology from the University of Rochester in 1976. He performed research with John Money via the Office of Psychohormonal Research at Johns Hopkins University School of Medicine.

Walker began a sex offender treatment program at the University of Texas Medical Branch in Galveston, Texas, in 1976. He also ran the Gender Clinic.
