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.

Your insurance company will also be able to inform you of any copayments, co–insurance, or deductibles that will be your responsibility. If you proceed in scheduling an appointment and your health insurance benefits do not participate with OHSU providers, your out of pocket liability may be higher. Visit the billing and insurance section of our site for more information.
