Dad and daughter's tower climb

In grief, in remembrance, in strength, and in love: September 11 has had a profound way of bringing lives together. Julianne Yotov never got to meet Firefighter Stephen Siller. She wasn't even born when the attacks happened on September 11, 2001. But every day on her way to school she passes Squad One, the firehouse where Siller began his final heroic hours that chaotic morning. That day Siller and so many other first responders risked and gave their lives to save others -- without question.
