I see patients at


I specialize in evaluating bone and soft tissue abnormalities. This extends beyond just cancer. I treat patients who have unusual X-ray or MRI findings, genetic abnormalities, infections and broken bones that require specialized treatment. I also do surgery for cancer and non-cancerous tumors. I treat patients of all ages. So far, my youngest patient was two months old and my oldest was 102. I enjoy working with patients to diagnose their problems and then setting up a treatment plan. I see many of my patients after treatment, either because we are watching for the return of a tumor or because we need to make sure they do not have problems with a reconstructive surgery over the years. This gives me a chance to get to know each person as an individual, beyond their medical problems.

In my spare time I like to be involved in athletics. I consider myself a distance runner and a swimmer, and am very active in USA swimming. I am a nationally certified official and travel throughout Oregon and Washington volunteering at swim meets. I have also built several cedar strip kayaks, and enjoy kayaking with my family.
