Madison was diagnosed with DIPG, a malignant brainstem tumor, on April 1, 2019. On December 2, 2021, after a 32 month battle with this monster of a cancer, Madison left her family and friends to become an angel. In an effort to celebrate Madison's birthday (September 21st) and NEVER let her be forgotten,  we will run, walk, and fight in Mighty Madison's name until a cure is found for DIPG.
