Addison Grace Holl was diagnosed with a very deadly form of pediatric cancer: diffuse intrinsic pontine glioma, or DIPG.
The diagnosis came on Addison's 7th birthday. At 8 years old, she died.
Despite losing their daughter, Addison's parents, Aaron and Kim Holl, are fighting for other children.
That is where the Addison Grace Defeat DPIG Foundation comes in.
