Oncology is an area of medicine that is a true group effort; involving multiple specialties combating cancer from different angles. The patient is an active participant in the process as well.

Ellis Ziel MD
Radiation Oncology

Ellis Ziel MD

Philosophy Of Care:

I believe in a patient-centered approach to cancer care and welcome the active input from patients and families on how to design a care plan that best fits their needs. I find that the more a patient understands about the complex disease process of cancer, the more motivated they are in fighting the disease. I'm so proud to be a part of North Star Lodge; we have a great team-based approach which supports the overall health and well-being of our patients. Having radiation oncology and medical oncology/hematology services located under one roof at North Star Lodge is such a benefit for our patients. I can walk right across the building to meet with other medical experts regarding treatment coordination and care instead of calling or emailing another facility for information. This is patient-centered care at its best.
