ABOUT ROCC
A coordinated team for complex radiation oncology needs
Radiation Oncology Care Connection is a clinical-services organization supporting radiation oncology practices, hospitals, and multi-site networks across the United States.
Radiation Oncology Care Connection is a clinical-services organization supporting radiation oncology practices, hospitals, and multi-site networks across the United States. ROCC brings together experienced medical physicists, medical dosimetrists, radiation-safety professionals, and operational support under one coordinated model.
The organization was built around a straightforward need: radiation oncology programs require dependable access to specialized expertise, but staffing, workload, location, and technology needs do not always align neatly with a traditional full-time hiring model.
Our Mission
To provide radiation oncology organizations with dependable expertise, continuity, and capacity while supporting safe, consistent, and efficient clinical operations.
Our Values
What guides our work
Clinical responsibility
We approach each assignment with respect for its clinical importance and the standards of the organization we support.
Accountability
Responsibilities, expectations, and communication pathways should be clear.
Continuity
Long-term familiarity with a center’s people, systems, and workflows creates value beyond completion of individual tasks.
Adaptability
Coverage models should evolve as organizations, technology, workload, and staffing needs change.
Professional collaboration
Effective support depends on strong relationships among physicians, physicists, dosimetrists, therapists, administrators, and other clinical personnel.
