There are so many different situations and circumstances that have shaped her experience in this industry and there are no signs of stopping! But this isn't just a job for her. After losing a parent to cancer at  17 years old, fighting cancer risks became personal. Dorothy wants to make sure no family goes through that kind of loss because of something we can prevent.
