Every child battling cancer deserves a fighting chance.

The D.O. Believe Foundation is dedicated to raising awareness and funding for children's cancer, with the primary focus on brain tumors; supporting the families and children fighting the disease; and spreading Dominic's message that anyone can be a superhero!



Become an advocate for our cause.

If you ever see a child fighting cancer, it will change your outlook on life forever.

Each year in the U.S. there are an estimated 15,780 children between the ages of birth and 19 years of age who are diagnosed with cancer.

Our foundation is growing, helping to fund more research with each year. We are able to give hope to the hopeless with the generous support of our advocates.

Heroes come in every shape and size. Find the hero in you, and become a volunteer or sponsor for our foundation.
