Tommy Schomaker celebrates 10 years after heart transplant

It's a story we've followed for the past 14 years: A little boy named Tommy Schomaker born with essentially half of a heart.

A lifesaving transplant. The chance to meet his heart donor's family. The chance to live.

Then, a day Tommy's family feared they would never see: his high school graduation, and a very special guest by his side.

This is the story of two families sharing one heart.
