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.

Karen Raymaakers RN, CON(C), is a former writer for Verywell Health covering leukemia and lymphoma. After the loss of her grandmother to breast cancer in 1983, Karen decided to become a nurse and devote her career to the care of cancer patients.

For the past several years, Karen has been a clinical nurse educator in Calgary, Alberta, Canada, educating patients as well as new and experienced nurses about leukemia, lymphoma, and other blood cancers.


Karen received her baccalaureate degree in nursing from The University of Calgary in Alberta, Canada.
