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.
R. Alex Hsi, M.D. Co-founder, Peninsula Cancer Center
Prior to opening the Peninsula Cancer Center, Dr. R. Alex Hsi worked for ten years in the Department of Radiation Oncology at Virginia Mason Medical Center in Seattle and was Section Head from 2003 to 2009. He received his M.D. from University of Michigan, Ann Arbor, and completed residencies in Internal Medicine at the University of Michigan and Radiation Oncology at the University of Pennsylvania.
Dr. Hsi specializes in the diagnosis and treatment of prostate cancer. He has authored multiple scientific publications on prostate cancer and worked to develop several new diagnostic and treatment techniques. He uses the latest technology for prostate seed brachytherapy called real time dosimetry. He is the most experienced physician in the Northwest utilizing a revolutionary new gel technology to reduce side effects from prostate radiation therapy called SpaceOAR hydrogel. Dr. Hsi is also actively developing a new prostate biopsy technique to improve patient safety, comfort, and diagnostic accuracy called MR fusion 3D mapping transperineal prostate biopsy.
Heath Foxlee, M.D.Radiation Oncologist
Dr. Heath Foxlee has practiced radiation therapy on the Olympic Peninsula for twenty years at a thriving practice that he founded and developed in Sequim, Wash. He initially trained and worked as an engineer in Michigan and earned a postdoctoral fellowship in Medical Informatics at University of California, San Francisco. While in San Francisco, he completed his residency in radiation oncology with rotations at the heavy charged particle facility at Lawrence Berkeley Laboratory, Stanford University, and The Institut Gustave Roussy in Paris.
Special interests in radiation therapy include wellness, geriatrics, and minimizing the side effects of treatment. His favorite part of his work is the relationship with patients. He pays special attention to communicating the details about the patient’s diagnosis so that they understand the process and are reassured. He is also particularly fond of the life stories that patients share with him. Dr. Foxlee is an avid swimmer and surf kayaker. He also loves to read, sail, and play disc golf.
Aaron Sabolch, M.D.Radiation Oncologist
Dr. Aaron Sabolch joined Peninsula Cancer Center in 2016. He graduated from the University of Michigan School of Medicine, where he also completed his residency at the Department of Radiation Oncology. Areas of special expertise include lung cancer, prostate cancer (external beam radiotherapy), central nervous system malignancies (brain and spinal tumors, both primary and metastatic), head and neck cancer, skin cancer, and adrenal cancer. Dr. Sabolch also specializes in the following techniques: stereotactic radiosurgery, stereotactic body radiotherapy, image guided radiotherapy, volumetric modulated arc therapy, and intensity modulated radiotherapy. As a physician, Dr. Sabolch’s goal is to provide the highest level of care in a manner consistent with an individual’s values, beliefs, and goals. To do so not only requires an up to date knowledge of the continuously evolving tools available in the battle against cancer, but it also necessitates an emotional openness to the needs of each unique patient. To this end, Dr. Sabolch strives to create a safe, healing environment, and be ever supportive of his patients during their journey from cancer patient to cancer survivor. Away from the office, Dr. Sabolch is in the process of exploring all the Pacific Northwest has to offer; he loves to hike, kayak, jog, and spend time with his wife and young children.
