What each team member does

Radiation oncologist

Your radiation oncologist is your physician and will meet with you once a week to review your progress and discuss any questions or concerns you may have. The radiation oncologists who provide clinical care at the SCCA Proton Therapy Center are all members of the University of Washington Physician Group and hold faculty positions within the UW School of Medicine.

Clinical nurse

Your care team nurse will provide day-to-day care and help coordinate any additional medical services you might need during your proton treatment, including: arranging for blood tests, scans, medical appointments or other services you need. Your clinical nurse is experienced in radiation therapy.

Radiation therapist

Your radiation therapist will confirm that you are positioned correctly. This will ensure your treatment is delivered precisely according to your physician’s treatment plan. They will deliver your daily treatment and will remain close by while you receive therapy.

Patient care coordinator

Patient care coordinators manage the exchange of your medical records, collect information for evaluating your individual care plan and schedule your initial consultation. They also assist you in understanding your insurance, Medicare or Medicaid coverage, and help coordinate your payment and manage your costs.

Medical dosimetrist

Your medical dosimetrist works with your physician to prepare a treatment plan specific to you. They calculate the angles and doses of proton energy required to treat your tumor, while ensuring your healthy tissue is exposed to as little radiation as possible. 

Medical physicist

A medical physicist monitors the equipment and procedures used in therapy. They run patient-specific checks on your treatment plan to be sure you receive the correct dose of protons targeted precisely to your tumor.

Patient navigator/concierge

The patient navigator/concierge greets you when you come to the Center and can help and answer questions regarding your non-medical needs. If you are traveling to Seattle for treatment, your patient navigator/concierge can help you locate transportation, lodging and other local services you may need. They also plan and coordinate educational and social programs for you, such as visits to local museums and arts organizations.
