Our team uses a collaborative approach to treating and caring for patients.
Meet The Team Here:
Sophia Bornstein, MD, PhD, is a board-certified radiation oncologist at MCMC’s Celilo Cancer Center.
As a board-certified radiation oncologist, Dr. Bornstein specializes in using radiation therapy to reduce the symptoms of or cure cancer, and in the overall care of patients with cancer. Dr. Bornstein has published extensively on several radiological and oncological topics and is known for her head and neck cancers research and early phase clinical trial development.
Dr. Bornstein earned her M.D. and Ph.D. at Oregon Health & Science University. She won multiple awards, scholarships, and grants, including the NIH (the Pre-Doctoral Training Grant), Radiological Society of North American Research Medical Student Grant, and Tartar Trust Fellowship. She completed her internship at Providence St. Vincent’s Medical Center and took her residency at OHSU’s Department of Radiation Medicine, where she started a resident-run palliative radiation program, taught radiobiology, and completed the American Board of Radiology Holman Research Pathway.
Before joining MCMC, Dr. Bornstein worked as a radiation oncologist in various settings, including as an assistant professor at OHSU, assistant professor at Weill Cornell Medical College in New York, and a temporary physician at multiple underserved communities throughout the country.
Dr. Bornstein says, “I feel honored to treat patients with cancer and counsel them through treatment. I value the relationships with my patients and their families and developing personalized treatment plans for my patients based on their needs and wishes.”
After 15 years in Portland, Dr. Bornstein is excited to transition to a community treatment setting with a strong patient focus and impressive provider expertise. In her free time, she enjoys hiking and wine tasting.
The Columbia Gorge was a natural fit for Dr. McCarthy, who grew up in a small town in Wyoming, and developed a love for the Northwest while attending medical school in Seattle. An outdoor enthusiast, Dr. McCarthy enjoys spending her free time as an equestrian, hiking, white water rafting, skiing, and traveling. She moved to Oregon in 2015, when she met and married a local man.
Family is a priority for Dr. McCarthy, who lives with her husband, Luke, and their beloved dogs. Dr. McCarthy decided to pursue a career in medicine when she felt drawn to science throughout her education, and loved the tactile nature of surgery.
Her surgical interests are breast surgery for cancer and benign disease, as well as minimally invasive laparoscopy, which includes foregut (stomach) antireflux procedures, colorectal procedures, gallbladder and more. She is also trained in thyroid and parathyroid disease.
Dr. McCarthy enjoys being able to see noticeable change in her patients, and loves that she can see her patients through a varying level of acuity. She is also currently working toward an advanced certification for breast imaging, biopsy and partial breast radiation.
Dr. Proctor says she feels a special connection to her patients with breast-related health issues. She enjoys being part of a multi-disciplinary team, with the common goal of delivering the highest level of care.
Dr. Stelzer is a leading expert in the application of intensity modulated radiation therapy (IMRT) the technology used at Celilo that shapes radiation beams more precisely to spare surrounding tissue.
