Marvin said the joy that he felt when he saw others receive their needed heart was something that helped him after his son's surgery.
"You walk by the rooms with people still waiting and you almost feel guilty that your son got one," said Marvin. "But then you remember how you felt when you saw someone else receive a transplant and you know they feel the same way."
Marvin added the joy that he and others felt was only possible because someone made the choice to be an organ donor.
"I really want to stress to people how important it is to be an organ donor," said Marvin. "It means so much to so many people, including our family."
