About me

As a medical oncologist who diagnoses and treats patients with cancer, I see patients with gastrointestinal (digestive system) cancers:

My main research interest is how tumors form and respond to treatment. By studying how they work, I hope to find specific molecules that can be targets for new cancer treatments.

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. 

Visit our billing and insurance page for more information.
