When their son wants to dress up as Princess Elsa, of course, these two gay dads from New York City are cool with it, right? In “Luca’s Journey,” Carlos Encinias tells the true story of parenting a gender-expansive child with his husband, and the resistance they encounter from surprising places. Jeffrey Solomon chats with Carlos about his family’s journey and the process of developing this story with Houses as part of “TRANSformation,” a series of storytelling workshops and performances exploring gender identity and family. We then speak with Judy Sennesh of PFLAG’S NYC TransFamilies project, a key community partner in the development of “TRANSformation.”
