Co-Founder, Peninsula Cancer Center
Radiation Oncologist/Center Director

Dr. Berit Madsen has worked in radiation oncology for 22 years and specializes in breast and gynecologic cancer, head and neck cancer, prostate external beam therapy, and stereotactic radiotherapy. Dr. Madsen first discovered her passion for radiation oncology as a student during her rotation at Stanford’s Department of Radiation Oncology. She was fascinated by the scientific and technologic demands of the field, as well as the meaningful way it allowed her to help patients facing cancer. After receiving her M.D. from Stanford and serving as head of radiation oncology at Virginia Mason (where she pioneered stereotactic radiotherapy for prostate cancer), Dr. Madsen made it her personal goal to open a cancer center to serve the Kitsap Peninsula. “Establishing Peninsula Cancer Center has been a dream of mine for years. When I worked in Seattle, I witnessed how difficult it was for my patients that were ill and fatigued to travel for care. Now, my patients can get quality care closer to home.” Outside of the office you are likely to find Dr. Madsen gardening or sea kayaking. She is also a voracious reader and modern art fan.
