Our residents come from diverse educational and personal backgrounds, but all share a passion for radiation oncology clinical practice and research. We are also fortunate to have two fellows as part of our department, specializing in brachytherapy and genitourinary (GU) radiation oncology.
We work and learn together — in a single residents’ room — and consider the camaraderie of the residents and fellows one of the major strengths of our residency program.
