Daniel KimDr. Kim graduated top of his class from Amherst College with degrees in neuroscience and music. He graduated with his M.D. and M.B.A., with honors, from Harvard Medical School and Harvard Business School, respectively. He was awarded the Michael E. Porter Leadership Award upon graduation and served as Senior Advisor to then-Mayor Marty Walsh, focusing on shaping economic and healthcare policy for the city of Boston and Commonwealth of Massachusetts. Dr. Kim completed his internal medicine internship at Harvard Medical School’s Brigham and Women’s Hospital. He completed his residency at the Harvard Radiation Oncology Program which included training at Massachusetts General Hospital, Dana Farber Cancer Institute, Brigham and Women’s Hospital, and Boston Children’s Hospital. He was elected Chief Resident at the Harvard Radiation Oncology Program, helping guide clinical and educational directives for the largest radiation oncology residency in the country. He continues to be actively involved in teaching medical students and residents through clinical training and research.

Dr. Kim is trained in all aspects of radiation oncology with experience in advanced radiation therapy modalities including proton radiotherapy, stereotactic radiosurgery (SRS), stereotactic ablative radiotherapy (SBRT/SABR), intensity modulated radiation therapy (IMRT), volumetric modulated arc therapy (VMAT), MRI-linear accelerator radiotherapy, adaptive radiotherapy, high-dose rate (HDR) brachytherapy, low-dose rate (LDR) brachytherapy, intraoperative radiotherapy (IORT), and radioisotope/radiopharmaceutical therapy. He treats patients with all types of cancers and his clinical interests include providing high-level multidisciplinary treatment for genitourinary cancers (prostate, bladder, testicular, kidney, penile, and other urologic cancers), CNS (brain and spine) benign and malignant tumors, and gastrointestinal cancers. He is one of the only physicians in the mid-Atlantic region who offers all modalities for prostate cancer treatment in his practice – proton radiotherapy, HDR brachytherapy, LDR brachytherapy, SBRT/SABR on the Cyberknife and linear accelerator, IMRT/VMAT, MRI-guided radiotherapy, radioisotope/radiopharmaceutical therapy, spacer gel placement, and fiducial marker placement.

Dr. Kim’s academic interests have been in translational science through developing novel biomarkers by analysis of annotated datasets and preclinical studies that inform clinical trial design. He has developed and helped activate phase I and II clinical trials. Dr. Kim has received grant funding through the American Association for Cancer Research (AACR) and Harvard Medical School. He also has research interests in improving tumor control probability while decreasing normal tissue effects using proton radiotherapy. He is one of a few physicians with training in proton radiosurgery and proton SBRT/SABR. He is widely published and has authored over forty peer-reviewed publications in journals such as the New England Journal of Medicine and Clinical Cancer Research. He has been invited to present his award-winning research at national and international meetings, including AACR, American Society of Clinical Oncology (ASCO), and American Society for Radiation Oncology (ASTRO). Dr. Kim serves as a reviewer for several journals including Cancer, Journal of Clinical Oncology – Precision Oncology, International Journal of Radiation Oncology – Biology – Physics, Journal of Urology, Journal of Neurosurgery, Journal of Gastrointestinal Oncology, Radiotherapy and Oncology, and Translational Oncology.

Dr. Kim is board certified in radiation oncology. He sees patients at the Inova Schar Cancer Institute. Outside of the clinic, Dr. Kim enjoys playing sports and spending time with his wife and children.



Dr. Kim is very caring, compassionate, and intelligent. Everyone at the cancer center made the 6 weeks of radiation so easy, they become like a second family.

Dr. Kim called me to check in with me during the weekend after my initial consult. I think he could tell that I was so overwhelmed about everything. I was so taken aback that a doctor would call on his weekend off to go over things with me and assure me of the plan going forward. Without a doubt, I knew he was the best possible doctor to take care of me and that is worth its weight in gold.

I’ve spent years coaching organizations on client service, and Dr. Kim and his team checks all the best boxes. Dr. Kim consistently provided his expertise and compassion during a very challenging time for me.

My husband has a very complicated cancer history that metastasized to his brain and lungs. We could tell that Dr. Kim spent a lot of time reviewing his history as he was very prepared for the discussion. We were able to get on a clinical trial thanks to Dr. Kim.
