San Diego (CNN) -- For many children fighting cancer, it can be extremely tough to make it to their chemotherapy appointments. Two-year-old Sisi Johnson has neuroblastoma and must travel as much as six times a week to Rady Children's Hospital in San Diego. But her mother doesn't have a car, and Sisi's compromised immune system means public transportation is off-limits. That's where Richard Nares comes in. Nares, who lost his son, Emilio, to cancer in 2000, started a program called "Ride With Emilio" to provide transportation for low-income families and their children battling cancer. "No child should miss their cancer treatment due to lack of transportation," Nares says.
