Father's Day is a time to thank the special men in our lives - our Fathers, Step-fathers, Grandfathers, Uncles, Brothers and those individuals whose guidance and sacrifice has shaped us in so many ways. It's also a time to remember those who aren't with us today, but whose memory lives on through the stories we share.

As the 9/11 Museum officially opens to the public today, I want to take a moment to acknowledge those who made this day possible. This has been a long journey and a collaborative effort that began just months after the attacks when families and others impacted gathered to discuss creating a fitting memorial.

David Brooks op-ed, "the Art of Presence" spoke to me. After the death of my son on 9/11 and the loss of a niece and nephew in other tragedies, I can associate with Catherine Woodiwiss' personal story. She eloquently articulates what so many families experience when they suffer a traumatic loss, whether they lost a loved one on 9/11, in a school natural disaster or a tragedy.
