The ChadTough Defeat DIPG Foundation funds the most innovative, promising research on DIPG, which is underfunded compared to most cancers.

The foundation’s co-founders, Jason and Tammi Carr and Mark and Jenny Mosier, are actively involved in the foundation’s governance and operations. Both the Carrs and the Mosiers lost their sons, 5-year-old Chad and 6-year-old Michael, in 2015 to this horrible disease.

In early 2021, The ChadTough Foundation and Michael Mosier Defeat DIPG Foundation united to become the ChadTough Defeat DIPG Foundation.

The new foundation remains committed to this same, shared mission. The new union significantly increases the potential of finding a cure for pediatric brain cancer more quickly by streamlining operations through a single nonprofit to fund more projects at a higher level.

The Carrs and Mosiers are joined by a growing, nationwide team of passionate Family Partners who are committed to changing the outcome for future families facing DIPG/DMG, in honor of their children.

While the survival rate for DIPG is still nearly 0%, doctors now believe a cure for DIPG is within reach. The ChadTough Defeat DIPG research program is guided by a Scientific Advisory Council made up of the leading experts in the field. The foundation will continue to be a part of this fight until DIPG is no longer a death sentence.


We see a world where kids diagnosed with DIPG/DMG have a bright future and can live out their dreams.


In the fight for a DIPG/DMG cure, we help patients and families by funding game-changing research and providing navigation throughout their journey.

Brain cancer is killing more kids than any other type of cancer. DIPG represents 10% of all pediatric brain tumors but nearly 50% of all pediatric brain cancer deaths.


These are the values that guide all that we do:

  • We are tough, because we have to be. We understand nothing about defeating DIPG/DMG is easy, but we choose to fight, inspired by kids like Chad and Michael who did not have a choice.
  • We are fueled by compassion for kids diagnosed with this devastating disease. Led by families who have walked this path, we are determined to help.
  • Family is sacred. We place family at the center of all we do.
  • We act with integrity, always. Our principles are guided by our ultimate respect for the children we have lost, the families we serve, and the children who have yet to be diagnosed.
  • We take our responsibility seriously. Every dollar matters. We are committed to making thoughtful decisions to maximize impact.
  • We are collaborative. We partner with others who share our passion because we believe working together and sharing knowledge is the fastest way to find a cure.
