They had been together for three years when they cofounded the Daughters of Bilitis (DOB) in San Francisco in 1955. This became the first social and political organization for lesbians in the United States and soon had a national reach. They both acted as president and until 1963 successively as editor of The Ladder magazine, which they also founded.

Both women worked to form the Council on Religion and the Homosexual (CRH) at Glide Memorial Methodist Church in northern California to persuade ministers to accept homosexuals into churches. The couple used their influence to decriminalize homosexuality in the late 1960s and early 1970s. They became politically active in San Francisco's first gay political organization, the Alice B.

Both women remained politically active, later serving in the White House Conference on Aging in 1995.
