About me

I am a surgeon who specializes in treating:

Colon, rectal and anal cancer are potentially curable for many, if not most, people. I provide custom care for each patient. Whether I’m seeing you for your first visit or a second opinion, I will learn what is important to you and make sure you understand your cancer and all treatment options.

For other conditions, I treat each patient individually, working with you to find the best treatment for your symptoms. We can often do this with office treatments and without surgery.

I joined OHSU in 2005. I am part of the OHSU Digestive Health Center and the OHSU Knight Cancer Institute.

My research interests include:

  • Treatment of rectal cancer without surgery
  • Hereditary colorectal cancer syndromes such as Lynch syndrome and familial adenomatous polyposis (FAP)

I started the state’s first colorectal cancer registry and have worked with other researchers at OHSU to continue our leadership in colorectal cancer research.

I am committed to providing top-quality individual care to each patient. Because of this, I’ve been recognized as one of “Portland’s Top Doctors" and one of "America’s Top Surgeons.”
