Dr. Showalter provides radiation treatment for patients with genitourinary, gynecologic, and pediatric cancers, melanoma and sarcoma.  His practice involves advanced external beam radiation therapy techniques, such as intensity-modulated radiation therapy (IMRT), image-guide radiation therapy, image-guided brachytherapy, prostate seed implants, and stereotactic body radiation therapy.

Research Interests

As a clinical researcher, Dr. Showalter is focused on improving outcomes for patients with high-risk prostate cancer, developing more effective and convenient radiation therapy schedules, and evaluating advanced technologies for brachytherapy and external beam radiation therapy.
