Dr. Shirnett Williamson has accepted a permanent position as a radiation oncologist at KRMC’s WL Nugent Cancer Center. Williamson has cared for WL Nugent patients as a temporary locums provider since May of 2025.
As a board-certified radiation oncologist, Williamson directs the use of therapeutic radiation to treat cancer patients. She works closely with medical oncology, surgery, and other specialties to create the best treatment plans for her patients.
Williamson has decades of experience in radiation oncology treatment, including as an instructor and clinical assistant professor for medical students and residents.
Williamson attended Howard University College of Medicine in Washington, DC, graduating in 1991. She then completed an internship in internal medicine before undergoing residency training in radiation oncology at Thomas Jefferson Hospital. After nearly a decade of practice in New Jersey for the University of Pennsylvania, Williamson went to the U.S. Virgin Islands, where she helped to establish a cancer center and radiation oncology program. After returning to the U.S., she served as medical director of radiation oncology for 10 years at Capital Health Medical Center in Pennington, New Jersey.
Williamson said it is important for her to be a comforting presence for patients undergoing cancer treatment. She added that listening with compassion to their concerns and involving them in their treatment plans is vital to her approach.
She said her patients and the team at WL Nugent inspired her to stay in Kingman. “I felt that I would be able to make a difference as part of the oncology team,” said Williamson. “I really felt at home.”
