As a brother who lost a sister to juvenile brain cancer as well, I have been searching for methods of helping the folks working on the problem. Outside of brain tumor non-profit foundations, have you found other channels to help? I am even thinking leaving ad-tech to work in bio-tech.
St. Bladrick's is my favorite organization for funding for research and they actually helped fund a project that actually turned out to be a great new treatment for children with neroblastoma (Which has killed several of our friends' children).
