“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.

She has been kind and caring throughout the whole process. So glad to have been on her team of breast cancer specialists. She takes time to listen to me and offer solutions. – Healthgrades

Very understanding explained in detail Staff is exceptional. – Healthgrades

Dr. Dunham was a wonderful surgeon, double mastectomy, she was very professional, very compassionate and compass oncology was also wonderful to deal through. I had no reconstruction and she was able to make a very straight line across the chest, don't laugh i have seen pictures of very bad horizontal lines and that was important to me. Her office has followed up even months after having the procedure. She knows what she is doing, don't hesitate to meet this wonderful person and have her as your surgeon. – Healthgrades

Dr. Dunham and her staff are all wonderful. Compassionate and very much a team. I felt I could call anytime to get answers to my questions and just plain old support from her well trained staff members. You're not just a number to Dr. Dunham. She's very caring and takes as much time as you need to answer your questions. – Healthgrades

Dr. Dunham and team provided seamless coordination for mastectomy. It's helpful that she works regularly with plastic surgeons she was able to recommend for reduction and reconstruction. I felt well-informed and prepared and appreciate that she has experience working on a variety of body types and sizes (which is not true of all surgeons I consulted with). I highly recommend her for breast cancer surgical options. – Healthgrades
