Peter B. Hardin MD, MS, BS | Speciality: Radiation Oncologist


Beginning first as an engineer, Dr. Hardin graduated with three degrees in engineering, both electrical and biomedical, from the University of Illinois Urbana-Champaign before entering medical school.  He pioneered surface coil designs for magnetic resonance imaging (MRI) equipment which are currently being used today to save patient’s lives.  He entered medical school to continue to further design medical equipment.  He found however that he could apply his background in engineering to the complexities and challenges of cancer therapy making radiation oncology a demanding specialty for which he is uniquely qualified.
