About me

I am a medical oncologist who specializes in diagnosis and treatment of adults with:

I also have experience with rare cancers such as pheochromocytoma, paraganglioma and adrenal cancer.

I specialize in chemotherapy, immunotherapy and team care for cancer with other specialists.

I take part in clinical trials and cancer research to improve patients’ survival and quality of life and to better understand these diseases.

I find it rewarding to help you understand your disease, provide a custom plan for you and support you through your treatment.

I grew up in upstate New York in a French-speaking family and go by Guillaume or Will, the English translation of my first name. Although I have spent most of my life on the East Coast, I was very excited to move to Portland, as were my wife and children.

Outside of work, I enjoy hiking, ice hockey and traveling with my family.

Insurance

Before scheduling an appointment

  1. Check your network. If you have health insurance,  call your company to find out if the OHSU Health location or provider you plan to visit is part of your network.
  2. Ask what you will pay. Your insurance company can tell you what your costs are likely to be.

If you schedule an appointment and your health insurance does not include OHSU Health, you may have to pay more than if you go to a provider in your insurance network.
