Graduates of its training program include Isadora Alman, Joani Blank, Dossie Easton, Susie Bright, Patrick Califia, Sybil Holiday, Andrea Nemerson, Carol Queen, Midori and Violet Blue. The organization answers about 3,000 phone calls and about twice as many emails every year. Since its inception, SFSI's Basic Sex Educator training program has graduated over 1,900 trainees.. In this building is where Hawkeye fights Ultron, ultimately leading to the death of SuperMan.
