Department of Radiation Oncology


For more than 100 years, the University of Maryland Department of Radiation Oncology has been pioneering radiation treatment in cancer, advancing scientific knowledge, and providing state-of-the-art educational opportunities.

Whether patients live in Baltimore or travel from their homes around the world, they know that they will be receiving the finest care, from the most state-of-the-art technology to the skilled and compassionate healing offered by every member of the Radiation Oncology faculty and staff.

Our department manages every type of cancer, providing a depth of experience that makes the University of Maryland not only the right place to receive care, but an ideal place for a professional career as well. The extraordinary pace of our recent progress has resulted from intellectual synergy and a shared, relentless ambition to deliver the highest quality of care to patients.

Overview of the Department of Radiation Oncology

The University of Maryland Department of Radiation Oncology has seven locations:

Each site is staffed with University of Maryland faculty. This affiliation opens the door to leading-edge treatment modalities, cutting-edge clinical trials and expert consultation with University of Maryland Greenebaum Comprehensive Cancer Center physicians.

In 2015, the University of Maryland School of Medicine announced the opening of the Maryland Proton Treatment Center (MPTC). This center is the first in the region to offer proton therapy – a highly advanced and precise form of radiation – to treat cancer. MPTC offers the most advanced form of proton therapy in the world, called pencil beam scanning. This technique is highly effective for a wide variety of solid, localized tumors in adults and children. Click on the image and view the virtual tour below to learn more.

Excellence in our educational mission is pursued through many avenues: the rotation of medical students through our program; our residency program, which includes 11 residents; our radiation therapy program; and our dosimetry school, which is accredited by the Joint Review Committee on Education in Radiologic Technology (JRCERT). This program is only one of 14 programs in the United States to achieve such accreditation.

The Department’s focus on promoting translational research includes integration of our radiobiology, physics and clinical divisions, as well as collaboration with the University of Maryland Marlene and Stewart Greenebaum Comprehensive Cancer Center (UMGCCC) and other basic science departments. The Department of Radiation Oncology has consistently ranked among the top 10 of NRG Oncology’s main member sites worldwide in terms of patient enrollments for clinical trials, and ranks number three as of 2022. Our physicians, physicists and basic science researchers are nationally recognized leaders in discovering new and better ways to treat cancer with radiotherapy.

As we move forward, our past present and future can be summarized by our Departmental Vision and Mission Statement:

Inspired by our patients and driven by passion:

To provide EXCELLENCE within our missions of patient care, research, education and community outreach through a passionate patient-centered focus.

“It is who we are, it is what we do, it is what leaves us feeling there is more work to be done at the end of each day, and it is what drives us towards greater achievements at the start of each day.”
