Our Physicians Will Always Deliver the Highest Quality Patient Care

Headed by the radiation oncologist, the team consists of several professionals who each play a vital role in the treatment process.

As a cancer specialist, the radiation oncologist is a physician who has training and experience in using radiation equipment and radioactive materials for the treatment of cancer. Medical physicists, who are specially trained in radiation physics, are responsible for calibrating and monitoring of all the radiation equipment used in treatments. Additionally, they assist the physician in formulating treatment plans that focus radiation on the tumor and limit the exposure of other organs to radiation.

After the radiation oncologist has prescribed the treatment, a radiation therapist, who has undergone extensive technological training, delivers the radiation treatments each day to the patient. Patients are regularly monitored by a physician, and in addition, a radiation therapy nurse may assist the patient with questions and any special needs throughout the course of treatment.



Our commitment is to provide each and every patient with the highest level of care, compassion and quality in the service we provide.
