St. Mary’s Hospital Radiation Oncology Center

SSM Health’s expansion into radiation oncology was driven by a clear goal: to deliver comprehensive, high-quality cancer care in one location—offering patients access to advanced treatment without leaving their community.

The new radiation oncology center serves as a natural extension of the existing hospital, which ERDMAN originally designed and built. With a focus on continuity of care, the center provides cutting-edge oncology services in a thoughtfully designed space that balances clinical precision with emotional comfort.

To support patients during some of their most vulnerable moments, the environment was shaped with intention—integrating natural light, calming views, and intuitive wayfinding to reduce stress and promote healing. This addition reinforces SSM Health’s commitment to whole-person care and ensures patients can navigate their cancer journey in a setting that feels both accessible and supportive.
