At Sibley Memorial Hospital, conveniently located in Washington, DC, highly respected radiation oncologists work with dedicated teams of experienced medical physicists, dosimetrists, therapists, and nurses to offer radiation treatment supported by the research and clinical expertise of Johns Hopkins. We take the time to explain the procedures, listen to your concerns, and answer all of your questions.

“Sibley’s radiation oncology department was already delivering excellent care. We plan to build on that reputation to create an elite cancer program in the DC metropolitan area to deliver state-of-the-art cancer care, innovate in the development of cancer treatments, and participate in the training of future leaders in cancer medicine and research,” says Irene Gage, MD, regional medical director of oncology for the Johns Hopkins National Capital Region (NCR).

As part of Johns Hopkins Medicine, the Sibley Radiation Oncology Department uses and contributes to the comprehensive safety program created at Johns Hopkins. As an international leader in radiation safety, our standards for safety serve as an example for other academic and community-based radiation practices. Not only do we employ the required equipment and treatment quality assurance protocols, we go well beyond those protocols by integrating innovative safety techniques developed by experts on our staff.

Patients at Sibley can also take part in Hopkins clinical trials and benefit from the pioneering research conducted at Hopkins. Sibley’s clinical team exchanges clinical and research trials with Hopkins staff, creating a seamless information-sharing network that benefits patients throughout the Baltimore-Washington, DC metropolitan region.
