Roger K. Strair, MD, PhD...he was the doctor who handled my stem cell transplant as part of my cancer treatment in 2001, and is the man most responsible for my being alive. If that doesn't qualify as being a hero, I don't know what does. Oh, and the anonymous people who donated the blood I needed for transfusions during treatment.
