This is Mark Schoneveld. Mark is a stay-at-home father of three beautiful children, a husband and a hero. Despite his own battle with brain cancer and the pain of the loss of a child, Mark has made it his mission to support cancer research and the AACR Foundation so that he might be alive as his children grow up and so others can have a chance at life. This Sunday Mark will be running his first marathon. As we kick off Philadelphia Marathon weekend, we are thinking of you, Mark. Sending all the love and great race vibes.
