Growing up in Hell’s Kitchen, Erin Lefevre realized that her younger brother Liam was “a little bit different from everyone else.”

He was constantly in and out of doctors’ offices as an infant. At 3 years old, he was told he was on the autism spectrum.

Ms. Lefevre had a hard time articulating her brother’s condition when she was a child. But today she is perfectly comfortable raising the issue. So much so that she has been sharing intimate moments from Liam’s everyday life through her documentary project “Liam’s World.”
