The father of New York’s first openly transgender firefighter opens up about his journey toward acceptance in this exclusive clip from the documentary, “Woman on Fire.”

A third generation firefighter, Brooke Guinan began identifying as trans in 2011, three years into her career at the New York City Fire Department. Her father, George William Guinan V, is an FDNY lieutenant and a 9/11 first responder. In “Woman on Fire,” he says he’s become one of his daughter’s biggest advocates in spite of his conservative political views and Christian faith.

“I suppose that she sensed there was not 100 percent acceptance by Mom and Dad. I’m supposing that could’ve been part of her motivation to take this job and want to do this job, to get closer to me because she knows how much I love it,” George William Guinan V says of Brooke’s decision to pursue a firefighting career. As a parent, he adds, “The only thing I can do is be as supportive as I can possibly be and as loving as I possibly can be towards this person who is my child.”
