John Bennett's three children, Ciara, Hunter and Tommy were born with Sanfilippo syndrome, a rare disease in which the body doesn't have the enzymes to digest sugar.
His youngest child, Tommy lost his battle to the disease in November of 2003. But the experimental treatment Tommy received at Duke University, inspired his dad to go to nursing school at Sacramento City College.
"It actually helps me take care of them better, we don't have to call the doctors as often; there are a lot of things that I know, and if I don't know, I can look up myself. It just makes everything a little easier," Bennett said.
Bennett worked 60 hours a week while going to school full time.
He will start looking for a nursing job this summer. He also wants to go on to get a bachelor's degree in science and nursing.
