Sara Ramirez, best known as out doctor Callie Torres on Grey’s Anatomy, came out as bisexual while addressing the True Colors: 40 to None Summit, a two-day seminar on LGBT youth homelessness.

”So many of our youth experiencing homelessness are youth whose lives touch on many intersections—whether they be gender identity, gender expression, race, class, sexual orientation, religion, citizenship status," Ramirez said at the gathering in Los Angeles Saturday morning.

"And, because of the intersections that exist in my own life: Woman, multi-racial woman, woman of color, queer, bisexual, Mexican-Irish American, immigrant, and raised by families heavily rooted in Catholicism on both my Mexican and Irish sides, I am deeply invested in projects that allow our youth's voices to be heard, and that support our youth in owning their own complex narratives so that we can show up for them in the ways they need us to."

Ramirez, who is married to husband Ryan DeBolt, played one of the few queer women on network television, but has mostly been private about her own sexuality.

In 2011, she told Latina magazine she had received hate mail for playing Callie and for supporting LGBT equality.

Ramirez left Grey's at the end of Season 12.

The True Colors Fund tweeted after Ramirez's speech, "We're so moved & inspired to see our dear friend/board member @SaraRamirez share her truth at our #40toNone Summit."

Note: An earlier version of this story referred to Ramirez's character on Grey's as a lesbian, not bisexual. We regret the error.
