Margaret Crawford, MSN, ANP, GNP

Margaret “Meggin” Crawford is an oncology nurse practitioner at the Calaway •Young Cancer Center. She completed her bachelor’s degree in nursing at the Johns Hopkins University School of Nursing in 1998, then moved on to finish her Master of Science in nursing at Case Western Reserve University in Cleveland, OH.

She has worked all over the world as a traveling nurse practitioner, from managing COVID testing in Punta Arenas, Chile, to serving as a primary care provider for rural tribal reservations in the Pacific Northwest. Most notably, however, she was one of two medical providers in the most remote clinics imaginable: Palmer Station in Antarctica, as well as at the South Pole itself. “It’s so extreme down there at the Pole, it feels like a mythical place,” she says. “There’s no wildlife, and literally everything in the entire world is above you. It was such an amazing adventure that very few people ever get to experience.”

For Meggin, nursing—and oncology specifically—represents a great opportunity to connect and help people. “You get to know patients over long periods in cancer treatment and provide this personalized level of support,” she says. “Most of us have been impacted by cancer at some point, including myself. Getting into this field was my attempt to make a difference in people’s lives, to help them over the long term with this huge hurdle.”

Before becoming a traveling nurse, Meggin worked for nearly seventeen years at the Baylor College of Medicine in Houston, Texas. “I came back to Colorado to be closer to family and to enjoy the incredible outdoor activities here,” she says. Cycling is her primary passion, though she loves to try new outdoor activities whenever she can. She also loves to read in her spare time and travel the world when her schedule permits.

Kelly worked at the University of Colorado Anschutz Medical Campus Blood Disorders Center as a nurse practitioner since 2012, accumulating experience in both inpatient and outpatient settings, working primarily with blood cancer patients and cellular therapy. She also helped lead education and onboarding for over four years, organized educational resources and clinical activities, and developed an onboarding curriculum for new advanced practice providers.

Kelly’s passion lies in improving her patients’ lives using the most current treatment options available. “There are new treatments and therapies that are more targeted and less toxic than traditional chemotherapy, and that’s very exciting to me,” she says. “We are now able to provide personalized treatments and therapies that improve care, comfort, and outcomes for each individual.”

Kelly lives with her husband, son, and their dog. The family loves mountain biking and running local trails, usually all together. The family enjoys traveling, with camping in Iceland, Portugal, and Switzerland being favorite recent adventures.
