Oncology Nurse




University of Calgary in Alberta, Canada


I see my role as a way to share my passion for leukemia and lymphoma nursing with a whole new audience. Instead of only sharing my knowledge with the clients I meet each day, I can reach out to anybody across the miles with just the click of a mouse.
