David's mother was diagnosed with brain cancer when he was in college. After her death, David started a support group for students coping with grief called Ailing Mothers and Fathers (AMF) based on his mother's initials. The group met regularly to share their experiences with loss and participate in fundraising events for cancer research. David graduated college and received advanced degrees with the goal of becoming an oncologist to honor his promise to his mother to help others dealing with loss.
