My mom is gay. But it took me a long time to say those words out loud. She came out nearly 20 years ago when I was in high school. My parents soon separated, and eventually, she married her longtime partner in one of Massachusetts’ first legal unions. It was a raw and difficult time. I hardly spoke to her for a year while I studied abroad. It felt like a fact that needed to be hidden, especially among my prep-school classmates. The topic was taboo even within our otherwise tight-knit family. Five years ago, at age 29, I embarked on a project to meet, photograph and interview people with similar stories. Despite living around the world, I had never encountered anyone else raised by a gay parent. My sister, living in San Francisco, connected me with the non-profit group, COLAGE, the only national organization focused on supporting those with L.G.B.T.Q. parents. I have since documented the stories of dozens of children and met many more. Each portrait and interview has become, in an unexpected way, my own therapy session. While my experience was difficult, I am hopeful that won’t be the case for the next generation.
