Oncology San Antonio

Your well-being and the optimum outcome for your diagnosis is our focus. We’ve established a multidisciplinary oncology group, which makes top specialists a part of the practice. You benefit from a focused, compassionate continuum of care within one medical group.

Oncology San Antonio is a private, physician-owned oncology practice that was established in 1974 by Phillip T. Voltz, Jr. MD, who later served as President of the Bexar County Medical Society. It was the first radiation oncology practice in San Antonio and is the longest-tenured private radiation facility in the city. The practice continues to provide compassionate, personalized cancer treatment enhanced by innovative, effective methodologies and caring connections with each patient. Oncology San Antonio has expanded to encompass medical oncology, hematology, integrative oncology, a comprehensive breast care program, and urology. We have grown, but our personal dedication to the healing arts remains the same.
