An Interview With John 'Gungie' Rivera, Founder, Cristian Rivera Foundation

John “Gungie” Rivera is putting a face on Diffuse Intrinsic Pontine Glioma (DIPG). It's the smiling face of his 6-year-old son, Cristian, who died of the rare disease on Jan. 25, 2009.

Forming the Cristian Rivera Foundation shortly after his son's death of the malignant brainstem tumor, Rivera and a team of volunteers donate 100 percent of donated funds to raise awareness about the disease and to find a cure.
