Dr. Dunham was named one of Portland's Top Medical Providers 2020 by Portland Monthly Magazine.

Dr. Dunham was named one of Portland's Top Docs & Nurses 2019 by Portland Monthly Magazine.

“Every patient’s journey through treatment is as unique as they are in every other aspect of life. So is their disease. My goal is to respect those differences and work together to make the best choices possible for each individual.”

Dr. Dunham is a fellowship trained breast surgical oncologist specializing in the surgical management of breast cancer and benign breast disease. She has advanced expertise in oncoplastic techniques in addition to skin and nipple sparing mastectomies. Her approach to care is very collaborative. She takes the time to help her patients understand what is happening so they can be comfortable and an active part of decision making. She believes strongly that there is not a formula in cancer care. The interpersonal experience is essential to care and ultimately healing.

In her spare time Dr. Dunham enjoys outdoor activities, traveling, and spending time with her husband and dog.
