About me

Stephen Ronson, MD, serves a medical director of radiation oncology at MedStar Franklin Square Medical Center. Working in collaboration with a multidisciplinary team of oncology experts, he specializes in the delivery of localized, highly-targeted radiation treatments for patients diagnosed with wide range of cancers. Dr. Ronson is skilled in the use of CyberKnife, a state-of-the-art technology that optimizes radiation treatment that can be used for many patients diagnosed with brain, lung, pancreatic, liver, bone, and prostate cancers. He also offers Intensity-Modulated Radiation Therapy (IMRT), Image-Guided Radiation Therapy (IGRT), Volumetric-Modulated Arc Therapy (VMAT), HDR Brachytherapy, Stereotactic Radiosurgery (SRS), and Stereotactic Body Radiation Therapy (SBRT).  Through MedStar Health’s clinical affiliation with Georgetown University, Dr. Ronson encourages patients who are eligible to participate in clinical trials, as a way of accessing the latest treatments available in the landscape of cancer care. He demonstrates a passion for helping his patients fight cancer, every day.

Dr. Ronson is board certified by the American Board of Radiology and is a member of the Radiation Oncology Affiliates of Maryland.

Dr. Ronson’s Philosophy of Care

“When I first meet with someone in consultation, I like to get to know them as a person, and not just a patient. It helps guide how we make treatment decisions. It also helps me understand how to educate patients and their families. What is most fulfilling about my work is having patients come back in for follow-up appointments – two, five, and ten years into remission. They are cancer free and tell me about their lives and families. That is what I find most rewarding.”
