Radiation Oncology

“Having everything in one place is great for patients, and it also helps us as providers because we get to combine our knowledge and work together. ”

— Dr. Blau

What brought you to cancer treatment?

I have always been interested in oncology and treating cancer because I have a parent who is an oncologist, but I found radiation oncology by accident. I was in my third year of medical school and taking care of a patient who had brain metastases. We worked with radiation oncology to get him treated very quickly, and I was really impressed with the communication and ease of working with the department as well as what we were able to do for the patient. It was a mix of hands-on work and technical skills, and I realized it would allow me to integrate a lot of different aspects of medical care into my practice.

What do you value about your work?

The part I find most fulfilling – and that I try to spend the most time on – is getting to know each individual patient so we can determine the best path forward together. Knowing people’s values and figuring out how these fit with the recommendations is so important.

Provider Background

Specialty: Radiation Oncology

Radiation oncology

I am a radiation oncologist who sees patients at the South Lake Union Clinic.

One of my mentors during training told me, “Cancer doesn’t always read the full book.” For each patient, the experience is unique. A lot of times, we may be seeing multiple patients for the same diagnosis, but there are a lot of different treatment paths.
