She was actively involved in the Coalition for Lesbian and Gay Rights, successfully lobbying for LGBT rights laws in New York City.
In 1987, Howard cofounded the New York Area Bisexual Network. She also founded the first chapter of Alcoholics Anonymous specifically for bisexual people. She successfully lobbied for the inclusion of bisexuality in the 1993 March on Washington at a time when the movement was focused on gay men and lesbians.
